Production Methods
Disodium edta may be prepared by the reaction of edetic acid and sodium hydroxide.

Manufacturing Process
10 mols of ethylene diamine as a 30% aqueous solution and 4 mols of solid caustic soda are placed in a steam heated kettle supplied with an agitator.
8 mols of sodium cyanide as a concentrated water solution (about 30%) are added and the solution heated to 60°C.
About a 10 inch vacuum is applied to bring the liquid to incipient boiling.
Formaldehyde (7.5 mols of 37% to 40% aqueous solution) is slowly added, the temperature being held at 60°C, and the solution vigorously stirred.
Then, when the evolution of ammonia has substantially stopped, an additional 8 mols of sodium cyanide, followed by 8 mols of formaldehyde are added as before.

This is continued until 40 mols of cyanide and 40 mols of formaldehyde have been added.
Then at the end about 2 mols more of formaldehyde are added, making 42 mols in all, to remove any last traces of cyanide.
About 8 to 10 hours are required to complete the reaction.
The resulting product, referred to herein as the crude reaction product, is essentially an aqueous solution of the sodium salt of ethylene diamine tetracetic acid.
To 1,000 g of the crude reaction product are added 264 g of ethylene diamine tetracetic acid.
The mixture is preferably heated to incipient boiling to increase the rate of reaction, and then the mixture is allowed to cool and crystallize.

The crystals formed are filtered off, washed with the smallest possible amount of ice water, and dried to a constant weight, which is 452 g.
A representative sample of the product so prepared showed, upon analysis, 13.26% sodium against a theoretical of 13.70% for the disodium salt.
The dialkali salt has a pH of about 5.3 and behaves like a weak acid, displacing CO2 from carbonates and reacting with metals to form hydrogen.
Disodium edta is a white crystalline solid.

EDTA is insignificantly absorbed through the skin, hardly metabolised and rapidly eliminated.
The safety margin for the use of EDTA in cosmetics is thus 300,000 times higher than the required minimum safety margin.

EDTA and its salts are irritating at high concentration levels, but they are only used at very low concentrations (< 0.5 %) in cosmetic products.
These concentrations are clearly below the irritation threshold.
Furthermore, the skin and eye compatibility of cosmetic products is being evaluated before it is placed on the market.

EDTA is not considered a persistent, bioaccumulative or toxic pollutant.
However, it is poorly biodegradable.
The European Commission considers that the risk linked to heavy metals only exists under particular circumstances, due to the trapping of EDTA/heavy metal complexes in sediments.

A salt of an organic acid (Ethylenediaminetetraacetic Acid, disodium salt) used in aqueous solutions with other reagents and inert materials for the preparation of cleaning mixtures and poultices to be applied to stone surfaces and frescoes.
EDTA disodium salt, for its property of complexing calcium within crusts and for its good solubility (better than tetrasodium salt), is used in the AB 57 poultice (I.C.R. formulation - Rome).
Disodium EDTA is besides a strong chelating agent of a great many metallic cations, as iron and copper; this property can be utilized to remove stains of rust or copper green from stone surfaces, wood, plasters, etc.

EDTA, Disodium Salt, Dihydrate is an extensively used chelator of divalent cations such as Ca2+.
EDTA (Ethylenediaminetetraacetic acid) is a chelating agent, a general chemical, and a sequestrant.
In molecular biology applications, Disodium EDTA is used to minimize metal ion contaminants.

Also, Disodium EDTA can facilitate enzymatic reactions that could be inhibited by heavy metal traces.
On the other hand, Disodium EDTA can inhibit enzymes, such as metalloproteases, that require divalent cations for activity.

EDTA disodium salt Na2H2 - 2H2O (dihydrate).
EDTA disodium salt is mainly used for its ability to bind to metal ions precipitating lead and other metals in solution, often used as a chelating agent in aquaria.
Together with iron sulphate heptahydrateis used to increase the amount of iron in aquariums.


USES OF DISODIUM EDTA:
Disodium EDTA (chemical formula - C10H16N2Na2O8) is a chelating agent, used to sequester and decrease the reactivity of metal ions that may be present in a product.
This white, water-soluble solid is widely used to bind to metal ions like iron and calcium ions and prevent the deterioration of cosmetics and personal care products.
Disodium EDTA thus enhances stability of cosmetics.

Disodium EDTA is widely used and can be found in moisturizers, skincare and cleansing products, personal cleanliness products, bath soaps, shampoos and conditioners, hair dyes, hair bleaches, and many other product types.
Disodium EDTA and the related ingredients bind to metal ions which inactivates them.
The binding of metal ions helps prevent the deterioration of cosmetics and personal care products thus enhancing their stability.

Disodium EDTA also helps to maintain clarity, protect fragrance compounds, and prevent rancidity.
Disodium EDTA is used up to 0.85% concentration in leave-on products.
For both skin care and hair care applications, Disodium EDTA prevents metal ions from depositing on the surface.

Disodium Phosphate Anhydrate What is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE)? Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is a food additive. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE)’s “generally recognized as safe” (GRAS) by the U.S. Food and Drug Administration (FDA) Phosphates like Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) are derived from the element phosphorus. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE)s are used to enhance food characteristics like nutritional value and cooking performance. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is used in packaged foods, including macaroni and pastas. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is also used in some cheeses as an emulsifier. You can also find it in meat products, canned sauces, Jell-O, evaporated milk, and some chocolate. Originally derived from animal bones and urine, phosphorus is now extracted from phosphate rock. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is purified and put through chemical reactions. Is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) safe? When it comes to food additives, it’s completely normal to wonder about safety. The FDA’s stance isn’t completely reassuring for some people. The Environmental Working Group (EWG) says there is a “fair” amount of data available on this phosphate. The EWG says that the additive can be considered safe. It’s not considered to be an environmental toxin or potentially harmful to humans. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is not bioaccumulative (where it accumulates within your body over time). Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is also classified as a “low human health priority” under Canadian law. In 2012, a studyTrusted Source was published declaring phosphates in general to be hazardous. The researchers suggested that all foods containing phosphates should be labeled as dangerous to public health. According to their research, accumulating phosphates in the body can cause organ calcification in people with renal failure, and even in people without kidney problems. But the International Food Additives Council states that inorganic phosphates have a long history of safe use in food and that additional studies have proven their safety. That being said, foods containing Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) are often packaged and heavily processed, so they’re not the healthiest choices to begin with. How to avoid Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) If you’re leery of Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) despite assurances of its safety, you can simply keep it out of your diet. However, identifying it may be difficult. In most cases, all you need to do is check the ingredients list on food packaging to tell if an item contains Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) or not. However, phosphates are also used in the meat industry to prevent spoilage, and meat packages don’t typically mention this. Avoiding packaged and processed foods is one way around Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE). Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) will benefit your overall health as well. Purchasing locally produced meats is another way to avoid Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE). Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) (DSP), or sodium hydrogen phosphate, or sodium phosphate dibasic, is the inorganic compound with the formula Na2HPO4. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is one of several sodium phosphates. The salt is known in anhydrous form as well as forms with 2, 7, 8, and 12 hydrates. All are water-soluble white powders; the anhydrous salt being hygroscopic. The pH of disodium hydrogen phosphate water solution is between 8.0 and 11.0, meaning it is moderately basic: Production and reactions Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) can be generated by neutralization of phosphoric acid with sodium hydroxide: H3PO4 + 2 NaOH → HNa2PO4 + 2 H2O Industrially Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is prepared in a two-step process by treating dicalcium phosphate with sodium bisulfate, which precipitates calcium sulfate: CaHPO4 + NaHSO4 → NaH2PO4 + CaSO4 In the second step, the resulting solution of monosodium phosphate is partially neutralized: NaH2PO4 + NaOH → HNa2PO4 + H2O Uses of Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is used in conjunction with trisodium phosphate in foods and water softening treatment. In foods, it is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is used as an anti-caking additive in powdered products. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is used in desserts and puddings, e.g. Cream of Wheat to quicken cook time, and Jell-O Instant Pudding for thickening. In water treatment, it retards calcium scale formation. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is also found in some detergents and cleaning agents. Heating solid Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) gives the useful compound tetrasodium pyrophosphate: 2 HNa2PO4 → Na4P2O7 + H2O Monobasic and dibasic sodium phosphate are used as a saline laxative to treat constipation or to clean the bowel before a colonoscopy. HPO42− + H2O ⇌ H2PO4− + OH− Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is a white, hygroscopic, odourless powder. Hydrated forms available include the dihydrate: a white crystalline, odourless solid; the heptahydrate: white, odourless, efflorescent crystals or granular powder; and the dodecahydrate: white, efflorescent, odourless powder or crystals. Although the concn of phosphate is low in the extracellular fluid, the anion is progressively concn in the renal tubule and represents the most abundant buffer system in the distal tubule. At this site, the secretion of H+ by the tubular cell in exchange for Na+ in the tubular urine converts disodium hydrogen phosphate to Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE). In this manner, large amt of acid can be excreted without lowering the pH of the urine to a degree that would block H+ transport by a high concn gradient between the tubular cell and luminal fluid. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is present in plasma and other extracellular fluid, in cell membranes and intracellular fluid, as well as in collagen and bone tissues. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) in the extracellular fluid is primarily in inorganic form and plasma levels may vary somewhat with age. The ratio of disodium phosphate and monosodium phosphate in the extracellular fluid is 4 to 1 (80% to 20%) at the normal pH of 7.4. This buffer ratio varies with the pH, but owing to its relatively low concentration, it contributes little to the buffering capacity of the extracellular fluid. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE), present in large amounts in erythrocytes and other tissue cells, plays a significant intracellular role in the synthesis of high energy organic phosphates. It has been shown to be essential to maintain red cell glucose utilization, lactate production, and the concentration of both erythrocyte adenosine triphosphate (ATP) and 2,3 diphosphoglycerate (DPG), and must be deemed as important to other tissue cells. NIOSH (NOES Survey 1981-1983) has statistically estimated that 1,230,592 workers (912,048 of these were female) were potentially exposed to Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) in the US(1). The NOES Survey does not include farm workers. Occupational exposure to Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) may occur through inhalation and dermal contact with this compound at workplaces where Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is produced or used(SRC). A great example of a chemical used in food production is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE). There are three main sodium phosphates used in food production: monosodium phosphate (NaH2PO4), Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) (Na2HPO4), and trisodium phosphate (Na3PO4). Though each form is useful in food processing, here we will focus on how Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) works in food production. What Is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE)? Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is made with a simple chemical reaction between phosphoric acid (H3PO4) and sodium hydroxide. Phosphoric acid is a mineral acid. It neutralizes with sodium hydroxide, which acts as an alkaline substance during the reaction. Sodium atoms replace two of the three hydrogen atoms in the phosphoric acid and Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is formed. When used according to the FDA’s good manufacturing practices, Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is generally recognized as safe. Though we often think of processed food as a byproduct of the mid-20th century, sodium phosphates have been used in food production for over a century. Phosphates were used in cheese production as early as 1895. Likewise, sodium phosphates have historically been used in processed cheese, evaporated milk, and other fluid milk products. pH Control In Packaged Foods Among the most common uses of Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is as a neutralizing agent. It acts as a buffering solution that helps control pH. Buffering solutions, a type of water-soluble solution known as aqueous solutions, are created by mixing a weak acid and its conjugate base. When a harsh acid or base is added to the solution, the pH of the solution as a whole is minimally affected. Many consumable liquids require diligent monitoring of pH to keep them in the right state. For instance, creamy milk can quickly become tangy cottage cheese by reducing the pH of the milk by adding an acid. Keeping the pH stable also contributes to food safety. Foods with a pH of 4.6 or lower do not provide a hospitable environment for bacteria like Clostridium botulinum to grow. Stabilizing Our Dairy Most people love cheese but making it would be difficult without Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE). It acts as an emulsifier that keeps fat and water from separating during the cheese-making process. This helps us get the richest and creamiest cheese possible. In evaporated milk, it helps keep the butterfat from separating in the can and prevents an unpleasant gel from forming. And if you are a fan of whipped cream, you can thank Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) for the pleasure of picking it up at your local grocery store. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is used as a processing agent in heavy whipping cream where it binds to the natural minerals in milk. It prevents the heavy cream from becoming unmanageable and coating the equipment during processing. Controlling Texture & Food Preservation Salt was the first preservative used to keep meat, seafood, pork, and poultry safe for consumption. Over time, food manufacturers have incorporated Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) as a means of food preservation. But the benefit of using Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) on meats does not stop at preservation. It can improve the meat’s tenderness and make it appear juicier. Americans are lucky enough to live in a world where rich foods are just a shopping trip away. And we have come to rely on these convenience foods. The world of chemistry allows food manufacturers to create safe, enjoyable products that make our lives easier. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is just one of the sodium phosphates used in the making of these packaged foods. But there are numerous other sodium phosphates used in and out of the food manufacturing industry. What is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE)? Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is the sodium salt derived from phosphate rock in the earth. What does it do? In mouthwash Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) acts as a buffering agent that helps maintain the pH or acidity of the product. When Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is combined with fluoride and phosphoric acid to form an acidulated phosphate fluoride solution as outlined in the FDA’s Anticaries monograph, that solution promotes remineralization and helps prevent enamel dissolution. How is Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) made? Our Model guides us to select ingredients which have been processed in a manner that supports our philosophy of human and environmental health. Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) is made by combining phosphoric acid, derived from phosphate rock, with soda ash. This material is then crystallized and purified for use in our products. What are the alternatives? For anticaries mouthwash products, with acidulated phosphate fluoride solution, Disodium phosphate anhydrate (disodyum fosfat anhidrat, DISODIUM PHOSPHATE ANHYDRATE) and phosphoric acid are required in conjunction with Sodium Fluoride per the Anticaries Drug Products for Over-the-Counter Human Use, Final Monograph.1 Tom’s offers both fluoride and fluoride free mouthwash options.

Sodium phosphate, dibasic appears as a colorless to white crystalline solid.
Disodium phosphate anhydrous (Food) is Soluble in water.
The primary hazard is the threat to the environment.

Immediate steps should be taken to limit spread to the environment.
Disodium phosphate anhydrous (Food) is Used as a fertilizer, in pharmaceuticals, in food processing, and for many other uses.


Also known as disodium hydrogen orthophosphate dodecahydrate, disodium phosphate dodecahydrate, sodium hydrogene dibasic.
Disodium phosphate anhydrous (Food) is a white powder that is highly hygroscopic and water soluble.
Disodium phosphate anhydrous (Food) is therefore used commercially as an anti-caking additive in powdered products.


Disodium phosphate anhydrous (Food) is Used as a pH buffer, stabilizer and emulsifier in processed cheese, condensed milk, instant pudding and other food applications.
The pH of disodium hydrogen phosphate water solution is between 8.0 and 11.0, meaning it is moderately basic:
HPO42− + H2O ⇌ H2PO4− + OH−

Disodium phosphate anhydrous (Food) is a white, powdered, non-aggressive and non-flammable substance.

Disodium phosphate anhydrous (Food) is often used as an emulsifier and a buffering agent for the production of processed cheese, as well as an additive to prevent the gelation of milk.
And addition of Disodium Phosphate Anhydrous can shorten the cooking time of pasta.


Disodium Phosphate, Anhydrous (DSPa) Granular & Powder is a white, odorless, free flowing powder.
This product is known for its alkalinity and is used as a buffering agent, protein modifier, stabilizer, and emulsifying agent.
DSP is commonly used during production of spray dried cheese and nonfat milk powders.

DSP protects the milk proteins from heat dehydration allowing the proteins to remain dispersed during the spray drying process, which assists in the solubility of the powders upon reconstitution with water.
DSP also stabilizes the emulsion to enhance flavor, body, and appearance of the final product.


Disodium phosphate anhydrous (Food) is made with a simple chemical reaction between phosphoric acid (H3PO4) and sodium hydroxide.
Phosphoric acid is a mineral acid.
Disodium phosphate anhydrous (Food) neutralizes with sodium hydroxide, which acts as an alkaline substance during the reaction.

Sodium atoms replace two of the three hydrogen atoms in the phosphoric acid and disodium phosphate is formed.
When used according to the FDA’s good manufacturing practices, disodium phosphate is generally recognized as safe.
Though we often think of processed food as a byproduct of the mid-20th century, sodium phosphates have been used in food production for over a century.

Phosphates were used in cheese production as early as 1895.
Likewise, sodium phosphates have historically been used in processed cheese, evaporated milk, and other fluid milk products.



pH Control In Packaged Foods:
Among the most common uses of disodium phosphate is as a neutralizing agent.
Disodium phosphate anhydrous (Food) acts as a buffering solution that helps control pH.
Buffering solutions, a type of water-soluble solution known as aqueous solutions, are created by mixing a weak acid and its conjugate base.

When a harsh acid or base is added to the solution, the pH of the solution as a whole is minimally affected.
Many consumable liquids require diligent monitoring of pH to keep them in the right state.
For instance, creamy milk can quickly become tangy cottage cheese by reducing the pH of the milk by adding an acid.

Keeping the pH stable also contributes to food safety.
Foods with a pH of 4.6 or lower do not provide a hospitable environment for bacteria like Clostridium botulinum to grow.


Stabilizing Our Dairy:
Most people love cheese but making it would be difficult without disodium phosphate.
Disodium phosphate anhydrous (Food) acts as an emulsifier that keeps fat and water from separating during the cheese-making process.
This helps us get the richest and creamiest cheese possible.


In evaporated milk, Disodium phosphate anhydrous (Food) helps keep the butterfat from separating in the can and prevents an unpleasant gel from forming.
And if you are a fan of whipped cream, you can thank disodium phosphate for the pleasure of picking it up at your local grocery store.
Disodium phosphate is used as a processing agent in heavy whipping cream where it binds to the natural minerals in milk.

Disodium phosphate anhydrous (Food) prevents the heavy cream from becoming unmanageable and coating the equipment during processing.


Controlling Texture & Food Preservation:
Salt was the first preservative used to keep meat, seafood, pork, and poultry safe for consumption.
Over time, food manufacturers have incorporated disodium phosphate as a means of food preservation.

But the benefit of using disodium phosphate on meats does not stop at preservation.
Disodium phosphate anhydrous (Food) can improve the meat’s tenderness and make it appear juicier.

Americans are lucky enough to live in a world where rich foods are just a shopping trip away.
And we have come to rely on these convenience foods.
The world of chemistry allows food manufacturers to create safe, enjoyable products that make our lives easier.

Disodium phosphate anhydrous (Food) is just one of the sodium phosphates used in the making of these packaged foods.
But there are numerous other sodium phosphates used in and out of the food manufacturing industry.


PRODUCTION AND REACTIONS OF DISODIUM PHOSPHATE ANHYDROUS (FOOD):
Disodium phosphate anhydrous (Food) can be generated by neutralization of phosphoric acid with sodium hydroxide:
H3PO4 + 2 NaOH → Na2HPO4 + 2 H2O

Industrially It is prepared in a two-step process by treating dicalcium phosphate with sodium bisulfate, which precipitates calcium sulfate:
CaHPO4 + NaHSO4 → NaH2PO4 + CaSO4

In the second step, the resulting solution of monosodium phosphate is partially neutralized:
NaH2PO4 + NaOH → Na2HPO4 + H2O



USES OF DISODIUM PHOSPHATE ANHYDROUS (FOOD):
It is used in conjunction with trisodium phosphate in foods and water softening treatment.
In foods, it is used to adjust pH.
Its presence prevents coagulation in the preparation of condensed milk.

It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid.All three hydrogens are acidic to varying degrees and can be lost from the molecule as H+ ions (protons). When all three H+ ions are removed, the result is an orthophosphate ion PO43−, commonly called "phosphate". Removal of one or two protons gives dihydrogen phosphate ion H2PO−4, and the hydrogen phosphate ion HPO2−4, respectively. Disodium phosphate dodecahydrate also forms esters, called organophosphates.Disodium phosphate dodecahydrate is commonly encountered in chemical laboratories as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. Although Disodium phosphate dodecahydrate does not meet the strict definition of a strong acid, the 85% solution can still severely irritate the skin and damage the eyes.The name "Disodium phosphate dodecahydrate " can be used to distinguish this specific acid from other "Disodium phosphate dodecahydrate ", such as pyrophosphoric acid. Nevertheless, the term "Disodium phosphate dodecahydrate " often means this specific compound; and that is the current IUPAC nomenclature.Disodium phosphate dodecahydrate is produced industrially by two general routes. In the wet process a phosphate-containing mineral such as calcium hydroxyapatite is treated with sulfuric acid.{\displaystyle {\ce {Ca5(PO4)3OH + 5H2SO4 -> 3H3PO4 + 5CaSO4v + H2O}}}{\displaystyle {\ce {Ca5(PO4)3OH + 5H2SO4 -> 3H3PO4 + 5CaSO4v + H2O}}} Fluoroapatite is an alternative feedstock, in which case fluoride is removed as the insoluble compound Na2SiF6. The Disodium phosphate dodecahydrate solution usually contains 23–33% P2O5 (32–46% H3PO4). It may be concentrated to produce commercial- or merchant-grade Disodium phosphate dodecahydrate , which contains about 54–62% P2O5 (75–85% H3PO4). Further removal of water yields Disodium phosphate dodecahydrate with a P2O5 concentration above 70% (corresponding to nearly 100% H3PO4). Calcium sulfate (gypsum) is produced as a by-product and is removed as phosphogypsum.To produce food-grade Disodium phosphate dodecahydrate , phosphate ore is first reduced with coke in an electric arc furnace, to make elemental phosphorus. Silica is also added, resulting in the production of calcium silicate slag. Elemental phosphorus is distilled out of the furnace and burned with air to produce high-purity phosphorus pentoxide, which is dissolved in water to make Disodium phosphate dodecahydrate .The Disodium phosphate dodecahydrate from both processes may be further purified by removing compounds of arsenic and other potentially toxic impurities.Food-grade Disodium phosphate dodecahydrate (additive E338) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. Soft drinks containing Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), which would include Coca-Cola, are sometimes called phosphate sodas or phosphates. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in soft drinks has the potential to cause dental erosion.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.Specific applications of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) include:In anti-rust treatment by phosphate conversion coating or passivation As an external standard for phosphorus-31 nuclear magnetic resonance.In Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) fuel cells.In activated carbon production.In compound semiconductor processing, to etch Indium gallium arsenide selectively with respect to indium phosphide.In microfabrication to etch silicon nitride selectively with respect to silicon dioxide.As a pH adjuster in cosmetics and skin-care products.As a sanitizing agent in the dairy, food, and brewing industries.A link has been shown between long-term regular cola intake and osteoporosis in later middle age in women (but not men).This was thought to be due to the presence of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), and the risk for women was found to be greater for sugared and caffeinated colas than diet and decaffeinated variants, with a higher intake of cola correlating with lower bone density.At moderate concentrations Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) solutions are irritating to the skin. Contact with concentrated solutions can cause severe skin burns and permanent eye damage.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is a unique inorganic acid electrolyte, which is generally used in fuel cell applications at around 200 °C in order to obtain higher system efficiency where its concentration is over 100%. A matrix, which is made of SiC, is used to retain the hot Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in a cell. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) has advantageous properties as an electrolyte, such as low volatility, good ionic conductivity, stability at relatively high temperatures, carbon dioxide tolerance, and also carbon monoxide tolerance. With all these advantages, there have been several technical electrolyte-related problems with fuel cell stacks. The major issues are volume change, evaporation loss, and electrolyte migration, and these are described in detail. These problems mainly arise due to the fact that Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is a liquid electrolyte under fuel cell operation.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) (H3PO4, also known as Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) or phosphoric (V) acid) is a mineral inorganic acid. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) refers to Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in which the prefix ortho is used to distinguish the acid from related Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), called polyphosphoric acids. Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), when pure, is a solid at room temperature and pressure. The most common source of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is an 85% aqueous solution that is colorless and nonvolatile but is sufficiently acidic to be corrosive. Because of the high percentage of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) in this reagent, at least some of the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is condensed into Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). For the sake of labeling and simplicity, the 85% represents the acid as if it was all Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). Dilute aqueous solutions of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) exist in the orthoform.Phosphoric acid (H3PO4) can be manufactured using either a thermal or a wet process. However, the majority of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is produced using the wet-process method. Wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is used for fertilizer production. Thermal process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is commonly used in the manufacture of high-grade chemicals, which require a much higher purity. The production of wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) generates a considerable quantity of acidic cooling water with high concentrations of phosphorus and fluoride. This excess water is collected in cooling ponds that are used to temporarily store excess precipitation for subsequent evaporation and to allow recirculation of the process water to the plant for reuse.In the wet process, Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (gypsum, CaSO4), which is separated from the reaction solution by filtration. Some facilities generally use a dihydrate process that produces gypsum in the form of calcium sulfate with two molecules of water (calcium sulfate dihydrate, CaSO4·2H2O). Other facilities may use a hemihydrate process that produces calcium sulfate with the equivalent of a half molecule of water per molecular of calcium sulfate (2CaSO4·H2O). The one-step hemihydrate process has the advantage of producing wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) with a higher concentration of phosphorus pentoxide (P2O5) and less impurities than the dihydrate process. A simplified reaction for the dihydrate process is as follows:In order to make the strongest pDisodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) possible and to decrease evaporation costs, 93% (v/v) sulfuric acid is normally used. During the reaction, gypsum crystals are precipitated and separated from the acid by filtration. The separated crystals must be washed thoroughly to yield at least a 99% (v/v) recovery of the filtered Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). After washing, the slurried gypsum is pumped into a gypsum pond for storage. Water is siphoned off and recycled through a surge cooling pond to the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) process. Wet-process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) normally contains 26%–30% (w/w) phosphorus pentoxide, and in most cases, the acid must be further concentrated to meet phosphate feed material specifications for fertilizer production. Depending on the types of fertilizer to be produced, Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) is usually concentrated to 40%–55% (w/w) phosphorus pentoxide by using two or three vacuum evaporators.In the thermal process, the raw materials for the production of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) are elemental (yellow) phosphorus, air, and water. The process involves three major steps: (1) combustion, (2) hydration, and (3) demisting. In the combustion step, the liquid elemental phosphorus is burned (oxidized) in ambient air in a combustion chamber at temperatures of 1650–2760°C (3000–5000°F) to form phosphorus pentoxide:The phosphorus pentoxide is then hydrated with dilute phosphoric acid (H3PO4) or water to produce strong Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) liquid.The final step is a demisting step that is applied to removal of the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) mist from the combustion gas stream before releasing to the atmosphere, which is usually accomplished by use of high-pressure-drop demisters. As always, release to the atmosphere can only be accomplished if the demisted product is a clean and nonpolluting stream.The concentration of phosphoric acid (H3PO4) produced from the thermal process normally ranges from 75% to 85% (v/v). This concentration is required for high-grade chemical production and other nonfertilizer product manufacturing. Efficient plants recover approximately 99.9% (w/w) of the elemental phosphorus burned as the phosphoric acid product.In Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) production, the fluorine released from reactors and evaporators is usually recovered as a by-product that can be sold. The remainder is passed to the condenser that produces a liquid effluent with mostly fluoride and small amounts of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). Closed systems recycle this effluent; in other cases, it is discharged to open waters.The manufacture of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) produces a gypsum slurry that is sent to settling ponds to allow the solids to settle out. About 5 lbs of phosphor-gypsum is generated per pound of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat). This phosphor-gypsum contains trace elements from phosphate rock, such as cadmium and uranium. Pond systems are usually fitted with lining systems and collection ditches to maintain control of trace elements and avoid contamination of ground water.The major source of phosphorus in the world is apatite, which is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of hydroxyl (OH−) ions, fluoride (F−) ions, and chloride (Cl−) ions, respectively, in the crystal apatite (Ca5(PO4)3(F,Cl,OH)). Commercially, the most important is fluoroapatite, a calcium phosphate that contains fluorine. This fluorine must be removed for the manufacture of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat), but it also can be used to produce hydrofluoric acid and fluorinated compounds.Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) esters, for example, tributyl phosphate, (CH3CH2CH2CH2O)3PO are used for the separation of nuclear fuel elements, uranium, zirconium and hafnium, and rare earth elements. Trioctyl phosphine oxide (TOPO), R3PO where R is C8H17) is another solvationg extractant used to recover uranium from wet process Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) liquors (Hudson, 1982). It is also used as a constituent of supported liquid membranes to recover rhenium from hydrometallurgical effluents (to be described in Chapter 12). Some long chain ketones, for example, methyl isobutyl ketone, CH3CO,CH2CH(CH3)2 have been used for separation of niobium and tantalum (described in Chapter 10).Conductivity An increase in Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) doping levels results in a clear increase in membrane conductivity related to the increase in proton ‘carriers’. Thus at 150 °C, for doping levels of 4.7, 6.7, and 14.5 Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, respective conductivities of 18, 22, and 79 mS cm−1 were obtained. On the contrary, it was observed that membrane conductivities increase up to 150 °C and then decline. This behavior was attributed to the self-dehydration of Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) above 150 °C, resulting in less conductive pyrophosphoric acid.At a doping level corresponding to the maximum protonation of PBI, i.e., two Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, the proton hopping from N site to the Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) anion was reported to contribute significantly to conductivity, which reached 25 mS cm−1 at 200 °C.On the contrary, at an acid doping level of 5.6 Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) moles per PBI repeat unit, ‘free acid’ contribution to conductivity is dominant. The conductivity of PBI was found to improve with atmospheric humidity, but its dependence on RH was far less than in Nafion membranes. This hopping-like mechanism is confirmed by Arrhenius behavior of conductivity.Hydration, too, releases some additional heat. The properties of phosphorus pentoxide and the absorption process inevitably leave as much as 25% of the oxide plus a Disodium phosphate dodecahydrate (Disodyum fosfat dodekahidrat) mist in the exit gases from the absorption tower. These are captured on passage through an electrostatic precipitator. By variations of the process details and equipment, grades (concentrations) of phosphoric acid from 75–105% (ortho, or superphosphoric acid) H3PO4 may be made in this manner.Phosphoric acid production by phosphorus combustion is usually accomplished in a stepwise manner as outlined, with intermediate isolation of the phosphorus. However, it may also be made by direct contact of phosphorus vapor from the furnace of a phosphorus plant with an air stream, and then passing the phosphorus pentoxide produced directly into a hydrator, without collection of the intermediate phosphorus as a liquid. Direct conversion to phosphoric acid in this way is attractive because the bulk of white phosphorus produced is converted to phosphoric acid.What is Phosphoric Acid? Phosphoric acid is a colorless, odorless mineral acid. With an acidic taste and somewhat viscous consistency, phosphoric acid is used in a wide variety of products and industries. Despite its popularity, this chemical can pose some potentially significant health hazards and should be handled with caution.Common Uses of Phosphoric Acid Phosphoric acid is used in several industries. Fertilizer accounts for the majority of phosphoric acid use, but this chemical can also be found in:Food additives (to acidify foods, or as a leavening agent) Soaps and detergents Water treatment Toothpastes Rust removal Etching solutions in dentistry Teeth whiteners Cleaning products Health Hazards Associated with Phosphoric Acid Phosphoric acid can be very hazardous in the case of skin contact, eye contact, and ingestion.

Anhydrous dibasic sodium phosphate occurs as a white powder. The dihydrate occurs as white or almost white, odorless crystals.The heptahydrate occurs as colorless crystals or as a white granular or caked salt that effloresces in warm, dry air. The dodecahydrate occurs as strongly efflorescent, colorless or transparent crystals.Either bone phosphate (bone ash), obtained by heating bones to whiteness, or the mineral phosphorite is used as a source of tribasic calcium phosphate, which is the starting material in the industrial production of dibasic sodium phosphate.Tribasic calcium phosphate is finely ground and digested with sulfuric acid. This mixture is then leached with hot water and neutralized with sodium carbonate, and dibasic sodium phosphate is crystallized from the filtrate.Dibasic sodium phosphate is used in a wide variety of pharmaceutical formulations as a buffering agent and as a sequestering agent. Therapeutically, dibasic sodium phosphate is used as a mild laxative and in the treatment of hypophosphatemia.Dibasic sodium phosphate is also used in food products; for example as an emulsifier in processed cheese.Dibasic sodium phosphate is widely used as an excipient in parenteral, oral, and topical pharmaceutical formulations. Phosphate occurs extensively in the body and is involved in many physiological processes since it is the principal anion of intracellular fluid. Most foods contain adequate amounts of phosphate, making hypophosphatemia (phosphate deficiency) virtually unknown except for certain disease states or in patients receiving total parenteral nutrition. Treatment is usually by the oral administration of up to 100 mmol of phosphate daily.Approximately two-thirds of ingested phosphate is absorbed from the gastrointestinal tract, virtually all of it being excreted in the urine, and the remainder is excreted in the feces.Excessive administration of phosphate, particularly intravenously, rectally, or in patients with renal failure, can cause hyperphosphatemia that may lead to hypocalcemia or other severe electrolyte imbalances. Adverse effects occur less frequently following oral consumption, although phosphates act as mild saline laxatives when administered orally or rectally. Consequently, gastrointestinal disturbances including diarrhea, nausea, and vomiting may occur following the use of dibasic sodium phosphate as an excipient in oral formulations. However, the level of dibasic sodium phosphate used as an excipient in a pharmaceutical formulation is not usually associated with adverse effects.LD50 (rat, oral): 17 g/kgThe anhydrous form of dibasic sodium phosphate is hygroscopic. When heated to 40℃, the dodecahydrate fuses; at 100℃ it loses its water of crystallization; and at a dull-red heat (about 240℃) it is converted into the pyrophosphate, Na4P2O7.

Benefits of Disodium pyrophosphate:
Controlled leavening acid
Prevents oxidation/colour change
Humectant
Buffering agent
Stabiliser
Acidulant

Functions of Disodium pyrophosphate:
Leavening acids provide air and volume to the baked good structure, but also affect the characteristics of the dough.
Besides reacting with baking soda to produce the gas carbon dioxide, these acids form ionic bonds with the starches and proteins in the dough.

Disodium pyrophosphate dissolves readily to form the anion pyrophosphate which interacts with the proteins in a baked good system to provide a moist texture.
Also, Disodium pyrophosphate provides a buffer system for the dough in the pH range 7.3-7.5, which influences the color of the baked product.

Advantages of Disodium pyrophosphate:
Widely available and economical thinner effective for treatment of cement contamination
Concentrated chemical that is effective at low treatment levels
Can be used with most water-base mud types

Preparation of Disodium pyrophosphate:
Disodium pyrophosphate is produced from sodium dihydrogenmonophosphate by heating at 200-250℃：
Na2CO3+2H3PO4→2NaH2PO4+H2O+CO2↑
2NaH2PO4→Na2H2P2O7+H2O

Disodium pyrophosphate is a condensed phosphate, commonly synthesized by the neutralization of phosphoric acid with sodium hydroxide or sodium carbonate at the ratio of 1:1 to produce monosodium phosphate (NaH2PO4), and then heated approximately 250°C to remove the water.
2 NaH2PO4 → Na2H2P2O7 + H2O

Production of Disodium pyrophosphate:

Commercial Production:
Disodium pyrophosphate is manufactured by partially neutralizing food grade phosphoric acid with sodium hydroxide or sodium carbonate to form monosodium phosphate.
Dehydration of monosodium phosphate at 250°C will form SAPP.
Currently, there is no known natural method for the production of Disodium pyrophosphate.

Origin of Disodium pyrophosphate:
In the eighteenth century and earlier, bakers relied upon yeast to leaven all baked goods.
However, using yeast for leavening baked goods was tedious and bakers began to explore the use of chemical leavening systems.
In 1846, baking soda was discovered as a leavening agent and that led to further discoveries of acids to react with baking soda, such as SAPP.

Commercially, Disodium pyrophosphate was introduced into baking powder blends towards the end of the nineteenth century.
Disodium pyrophosphate is a preferred leavening acid because Disodium pyrophosphate is less expensive and stronger than other leavening acids introduced previously.

The Copper (II) sulfate dissolves to give the cupric ion; in regard to a redox reaction with the thiosulfate, the cupric particles act like oxidizing agents.

Disodium salt is an inorganic sodium salt composed of sodium and thiosulfate ions in a 2:1 ratio.
Disodium salt has a role as an antidote to cyanide poisoning, a nephroprotective agent and an antifungal drug.
Disodium salt contains a thiosulfate(2-).

Disodium salt is an industrial chemical which also has a long medical history.
Disodium salt was originally used as an intravenous medication for metal poisoning.

Disodium salt has since been approved for the treatment of certain rare medical conditions.
These include cyanide poisoning, calciphylaxis, and cisplatin toxicity.

In vitro assays have demonstrated that Disodium salt is an anti-inflammatory and neuroprotective agent.
Disodium salt therefore has potential for treating neurodegenerative diseases such as Alzheimer disease and Parkinson disease.

NaSH has similar properties and is somewhat more powerful than Disodium salt in these in vitro assays.
However Disodium salt has already been approved as an orally available treatment.
Disodium salt may therefore be a readily available candidate for treating neurodegenerative disorders such as Alzheimer disease and Parkinson disease.

Disodium salt is an industrial compound which has a long history of medical use.

Since Disodium salt is employed as a food preservative, the general population is widely exposed to this non-toxic compound.
For example, Disodium salt is typically added to table salt at less than 0.1% and to alcoholic beverages at less than 0.0005%.
Disodium salt is generally available as a non-prescription oral product.

Disodium salt is an inorganic sodium salt with the formula Na2S2O3 composed of a 2:1 mixture of sodium and thiosulfate ions.

Disodium salt solutions are almost exclusively used to standardize Iodine solutions or as back-titrants in titrations using Iodine.
Solutions of Disodium salt are most commonly standardized with Potassium Dichromate or Potassium Iodate solutions, which generate Iodine from Iodide.
Starch indicator is typically used.

The reaction with Iodine is:
I3- + 2 S2O32- → 3 I- + S4O62- (Dithionite ion)

Titrations with standard Disodium salt solution are best conducted in the pH 5 - 9 range.
Since this is not always possible, the titrations should be conducted rapidly and with adequate stirring to insure rapid reaction of the Thiosulfate, thus minimizing any acid-accelerated decomposition.
This will also minimize the acid-catalyzed oxidation of Iodide (usually present in a titration involving Thiosulfate) to Iodate, which could lead to decreased accuracy.

Disodium salt solutions are subject to bacterial decomposition and chemical deterioration.
Disodium salt solutions decompose in acid solution resulting in the evolution of Sulfur Dioxide gas and precipitation of elemental Sulfur.
Contact with Carbon Dioxide in the air can produce the acidity leading to this decomposition, which is faster in more dilute Thiosulfate solutions.

Disodium salt, also known as sodium hydrosulfite, is used as an antidote to cyanide poisoning, but several studies have demonstrated that Disodium salt efficacy in some pathological conditions is related to ectopic calcification.
The mechanisms of action, by which Disodium salt exerts Disodium salt inhibitory effect on vascular mineralization, are not yet clear.

Disodium salt has been postulated that Disodium salt: (i) forms with calcium a more soluble complex than calcium phosphate and calcium oxalate, (ii) has antioxidant activity improving endothelial function, (iii) has acidosis properties.
However, O'Neil and Hardcastle demonstrated that the inhibitor effect of Disodium salt seems to be independent on calcium interactions or on pH, but could be due to a direct extracellular effect on calcification induced by cellular injury releasing cell debris and matrix vesicles.

Nevertheless, Disodium salt is used to treat calciphylaxis, kidney stones, uremic vascular calcification and coronary artery calcification.
Recently, intravenous Disodium salt has been used in a young boy with several deleterious mutations in ABCC6, ENPP1 and HBB genes and, over a period of 6 months, calcific stenosis of celiac and mesenteric arteries was not anymore detectable on arterial ultrasonography.
Follow-up evidenced a temporary efficacy of Disodium salt.

Two clinical trials highlight that Disodium salt treatment can be safe and can reduce the rate of coronary artery calcification progression in hemodialysis patients.

Disodium salt may be used to lessen some of the side effects of cisplatin (a cancer medicine).
Disodium salt is also used with another medicine in the emergency treatment of cyanide poisoning.

Disodium salt is also used to reduce the risk of hearing loss in children 1 month of age and older who are receiving medicines (eg, cisplatin) for cancer that have not spread throughout the body.
This medicine is to be given only by or under the immediate supervision of your doctor.

Photographic processing:
Silver halides, e.g., AgBr, typical components of photographic emulsions, dissolve upon treatment with aqueous thiosulfate.
This application as a photographic fixer was discovered by John Herschel.

Disodium salt is used for both film and photographic paper processing; the Disodium salt is known as a photographic fixer, and is often referred to as 'hypo', from the original chemical name, hyposulphite of soda.
Ammonium thiosulfate is typically preferred to Disodium salt for this application.

Neutralizing chlorinated water:
Disodium salt is used to dechlorinate tap water including lowering chlorine levels for use in aquariums, swimming pools, and spas (e.g., following superchlorination) and within water treatment plants to treat settled backwash water prior to release into rivers.
The reduction reaction is analogous to the iodine reduction reaction.

In pH testing of bleach substances, Disodium salt neutralizes the color-removing effects of bleach and allows one to test the pH of bleach solutions with liquid indicators.
The relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (the active ingredient in bleach) and in so doing becomes oxidized to sulfate.

The complete reaction is:
4 NaClO + Na2S2O3 + 2 NaOH → 4 NaCl + 2 Na2SO4 + H2O

Similarly, Disodium salt reacts with bromine, removing the free bromine from the solution.

Thiosulfate anion readily reacts with the dilute acids producing sulphur, sulphur dioxide and also water.
The chemical has a density measuring about 1.667 g/mL.

Structure of Disodium salt:
Two polymorphs are known as pentahydrate.
The anhydrous salt exists in several polymorphs.

In the solid state, the thiosulfate anion is tetrahedral in shape and is notionally derived by replacing one of the oxygen atoms by a sulfur atom in a sulfate anion.
The S-S distance indicates a single bond, implying that the terminal sulfur holds a significant negative charge and the S-O interactions have more double-bond character.

Disodium salt has a chemical formula of Na2S2O3 and the molar mass of about 158.11 g/mol.
Disodium salt well exists in the form of pentahydrate salts (Na2S2O3.5H2O), having a molar mass measuring about 248.18 g/mol.

The Disodium salt is an ionic compound which consists of two cations of sodium atom (Na+) and a negatively charged anion of thiosulfate (S2O3-).
Here the central atom consisting of sulphur bonds to the three oxygen atoms and also another atom of sulphur, all these through a single and also double bonds possessing resonance character.
The solid also exists in a monoclinic crystalline structure.

The thiosulfate anion is usually a tetrahedral structure and, is obtained by the replacement of one of the atoms of oxygen by the use of sulfur atom in the sulfate anion.

Production of Disodium salt:
On an industrial scale, Disodium salt is produced chiefly from liquid waste products of sodium sulfide or sulfur dye manufacture.

In the laboratory, this salt can be prepared by heating an aqueous solution of sodium sulfite with sulfur or by boiling aqueous sodium hydroxide and sulfur according to this equation:
6 NaOH + 4 S → 2 Na2S + Na2S2O3 + 3 H2O

Principal reactions of Disodium salt:

Upon heating to 300 °C, Disodium salt decomposes to sodium sulfate and sodium polysulfide:
4 Na2S2O3 → 3 Na2SO4 + Na2S5

Thiosulfate salts characteristically decompose upon treatment with acids.
Initial protonation occurs at sulfur.

When the protonation is conducted in diethyl ether at −78 °C, H2S2O3 (thiosulfuric acid) can be obtained.
Disodium salt is a somewhat strong acid with pKas of 0.6 and 1.7 for the first and second dissociations, respectively.

Under normal conditions, acidification of solutions of this salt excess with even dilute acids results in complete decomposition to sulfur, sulfur dioxide, and water:
8 Na2S2O3 + 16 HCl → 16 NaCl + S8 + 8 SO2 + 8 H2O

Coordination chemistry:
Thiosulfate is a potent ligand for soft metal ions.
A typical complex is [Pd(S2O3)2(ethylenediamine)]2−, which features a pair of S-bonded thiosulfate ligands.

Disodium salt and ammonium thiosulfate have been proposed as alternative lixiviants to cyanide for extraction of gold.
The advantages of this approach are that (i) thiosulfate is far less toxic than cyanide and (ii) that ore types that are refractory to gold cyanidation (e.g. carbonaceous or Carlin-type ores) can be leached by thiosulfate.
Some problems with this alternative process include the high consumption of thiosulfate, and the lack of a suitable recovery technique, since [Au(S2O3)2]3− does not adsorb to activated carbon, which is the standard technique used in gold cyanidation to separate the gold complex from the ore slurry.

Iodometry:

In analytical chemistry, the most important use comes because the thiosulfate anion reacts stoichiometrically with iodine in aqueous solution, reducing Disodium salt to iodide as the thiosulfate is oxidized to tetrathionate:

2 S2O2−3 + I2 → S4O2−6 + 2 I−

Due to the quantitative nature of this reaction, as well as because Na2S2O3·5H2O has an excellent shelf-life, Disodium salt is used as a titrant in iodometry.
Na2S2O3·5H2O is also a component of iodine clock experiments.

This particular use can be set up to measure the oxygen content of water through a long series of reactions in the Winkler test for dissolved oxygen.
Disodium salt is also used in estimating volumetrically the concentrations of certain compounds in solution (hydrogen peroxide, for instance) and in estimating the chlorine content in commercial bleaching powder and water.

Aluminium cation reaction:
Disodium salt is used in analytical chemistry.

Disodium salt can, when heated with a sample containing aluminium cations, produce a white precipitate:
2 Al3+ + 3 S2O2−3 + 3 H2O → 3 SO2 + 3 S + 2 Al(OH)3

Organic chemistry:
Alkylation of Disodium salt gives S-alkylthiosulfates, which are called Bunte salts.
The alkylthiosulfates are susceptible to hydrolysis, affording the thiol.

This reaction is illustrated by one synthesis of thioglycolic acid:
ClCH2CO2H + Na2S2O3 → Na[O3S2CH2CO2H] + NaCl
Na[O3S2CH2CO2H] + H2O → HSCH2CO2H + NaHSO4
