The reported transition temperatures vary substantially from source to source.
When heated above 140 °C, Boric Acid (Ortho Boric Acid) yields metaboric acid (HBO2) with loss of one water molecule:
B(OH)3 → HBO2 + H2O
Heating metaboric acid above about 180 °C eliminates another water molecule forming tetraboric acid, also called pyroboric acid (H2B4O7):
4 HBO2 → H2B4O7 + H2O
Further heating (to about 530 °C) leads to boron trioxide:
H2B4O7 → 2 B2O3 + H2O
Aqueous solution
When Boric Acid (Ortho Boric Acid) is dissolved in water, it partially dissociates to give metaboric acid:
B(OH)3 ⇌ HBO2 + H2O
The solution is mildly acidic due to ionization of the acids:
B(OH)3 + H2O ⇌ [BO(OH)2]− + H3O+
HBO2 + H2O ⇌ [BO2]− + H3O+
However, Raman spectroscopy of strongly alkaline solutions has shown the presence of [B(OH)4]− ions, leading some to conclude that the acidity is exclusively due to the abstraction of OH− from water:
B(OH)3 + HO− ⇌ B(OH)−4
Equivalently,
B(OH)3 + H2O ⇌ B(OH)−4+ H+ (K = 7.3×10−10; pK = 9.14)
Or, more properly,
B(OH)3 + 2 H2O ⇌ B(OH)−4 + H3O+
This reaction occurs in two steps, with the neutral complex aquatrihydroxyboron B(OH)3(OH2) as an intermediate:
B(OH)3 + H2O → B(OH)3(OH2)
B(OH)3(OH2) + H2O + HO− → [B(OH)4]− + H3O+
This reaction may be characterized as Lewis acidity of boron toward [HO]−, rather than as Brønsted acidity.
However, some of its behaviour towards some chemical reactions suggest Boric Acid (Ortho Boric Acid) to be tribasic acid in the Brønsted sense as well.
Boric Acid (Ortho Boric Acid), mixed with borax Na2B4O7·10H2O (more properly Na2B4O5(OH)4·8H2O) in the weight ratio of 4:5, is highly soluble in water, though they are not so soluble separately.
SULFURIC ACID SOLUTION OF BORIC ACID (ORTHO BORIC ACID):
Boric Acid (Ortho Boric Acid) also dissolves in anhydrous sulfuric acid according to the equation:
B(OH)3 + 6 H2SO4 → [B(SO4H)4]− + 2 [HSO4]− + 3 H3O+
Boric Acid (Ortho Boric Acid) is an extremely strong acid, even stronger than the original oleum.
ESTERIFICATION OF BORIC ACID (ORTHO BORIC ACID):
Boric Acid (Ortho Boric Acid) reacts with alcohols to form borate esters, B(OR)3 where R is alkyl or aryl.
The reaction is typically driven by a dehydrating agent, such as concentrated sulfuric acid:
B(OH)3 + 3 ROH → B(OR)3 + 3 H2O
With vicinal diols
The acidity of Boric Acid (Ortho Boric Acid) solutions is greatly increased in the presence of cis-vicinal diols (organic compounds containing similarly oriented hydroxyl groups in adjacent carbon atoms, (R1,R2)=C(OH)−C(OH)=(R3,R4)) such as glycerol and mannitol.
The tetrahydroxyborate anion formed in the dissolution spontaneously reacts with these diols to form relatively stable anion esters containing one or two five-member −B−O−C−C−O− rings.
For example, the reaction with mannitol H(HCOH)6H, whose two middle hydroxyls are in cis orientation, can be written as
B(OH)3 + H2O ⇌ [B(OH)4]− + H+
[B(OH)4]− + H(HCOH)6H ⇌ [B(OH)2(H(HCOH)2(HCO−)2(HCOH)2H)]− + 2 H2O
[B(OH)2(H(HCOH)2(HCO−)2(HCOH)2H)]− + H(HCOH)6H ⇌ [B(H(HCOH)2(HCO−)2(HCOH)2H)2]− + 2 H2O
Giving the overall reaction
B(OH)3 + 2 H(HCOH)6H ⇌ [B(H(HCOH)2(HCO−)2(HCOH)2H)2]− + 3 H2O + H+
The stability of these mannitoborate ester anions shifts the equilibrium of the right and thus increases the acidity of the solution by 5 orders of magnitude compared to that of pure boric oxide, lowering the pKa from 9 to below 4 for sufficient concentration of mannitol.
The resulting solution has been called mannitoboric acid.
The addition of mannitol to an initially neutral solution containing Boric Acid (Ortho Boric Acid) or simple borates lowers its pH enough for it to be titrated by a strong base as NaOH, including with an automated a potentiometric titrator.
This property is used in analytical chemistry to determine the borate content of aqueous solutions, for example to monitor the depletion of Boric Acid (Ortho Boric Acid) by neutrons in the water of the primary circuit of light-water reactor when the compound is added as a neutron poison during refueling operations.
PREPARATION OF BORIC ACID (ORTHO BORIC ACID):
Boric Acid (Ortho Boric Acid) is produced from borax, colemanite, or other inorganic borates by reaction with sulfuric acid or hydrochloric acid, and cooling the solution to proper temperature:
Na2B4O7 ? 10Η2Ο + H2SO4 → 4H3BO3 + Na2SO4 + 5H2O
Boric Acid (Ortho Boric Acid) also may be prepared by extraction of weak borax brine with a kerosene solution of an aromatic diol, such as 2-ethyl-1,3-hexanediol or 3-chloro- 2-hydroxy-5-(1,1,3,3-tetramethylbutyl)benzyl alcohol.
The diol-borate chelate formed separates into a kerosene phase.
Treatment with sulfuric acid yields Boric Acid (Ortho Boric Acid) which partitions into aqueous phase and is purified by recrystallization.
PRODUCTION METHODS OF BORIC ACID (ORTHO BORIC ACID):
Boric Acid (Ortho Boric Acid) occurs naturally as the mineral sassolite.
However, the majority of Boric Acid (Ortho Boric Acid) is produced by reacting inorganic borates with sulfuric acid in an aqueous medium.
Sodium borate and partially refined calcium borate (colemanite) are the principal raw materials.
When Boric Acid (Ortho Boric Acid) is made from colemanite, the fineground ore is vigorously stirred with mother liquor and sulfuric acid at about 908℃.
The by-product calcium sulfate is removed by filtration, and the Boric Acid (Ortho Boric Acid) is crystallized by cooling the filtrate.
