Preparation
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
Diborane
B2H6 + 6 H2O → 2 B(OH)3 + 6 H2
BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)
