Question

synthesis of boric acid from borax principal ​

Answer 1

Explanation:

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 H.
