Answer 1

Answer:

Explanation:

When borax is used for cleaning because on dissolving in water it gives alkaline sollution.... When borax is dissolved in water it ionizes and hydrolysis of borate iongives OH (the hydroxyl ion) and boric acid

Answer 2

Answer: when borax, Na2B4O7, is dissolved in water, it hydrolyzes to form sodium borate NaB(OH)4, and boric acid, which can be written as B(OH)3 or H3BO3.

Explanation:

Na2B4O7 + 7H2O → 2NaOH + 4H3BO3

 Orthoboric acid                                    

Since boric acid is a  weak acid and NaOH is  a  strong base the resultant solution of Borax is basic in nature.
