Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and
acidum boricum, is a weak, monobasic Lewis acid of boron, which is often
used as an antiseptic, insecticide, flame retardant, neutron absorber, or
precursor to other chemical compounds. It has the chemical formula H3BO3
(sometimes written B(OH)3), and exists in the form of colorless crystals or a
white powder that dissolves in water. When occurring as a mineral, it is called
Boric acid may be prepared by reacting borax (sodium tetraborate
decahydrate) with a mineral acid, such as hydrochloric acid:
Na2B4O7·10H2O + 2 HCl → 4 B(OH)3 [or H3BO3] + 2 NaCl + 5 H2O
It is also formed as a by product of hydrolysis of boron trihalides and
B2H6 + 6 H2O → 2 B(OH)3 + 6 H2
BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)
