Answer:

hope it helps you

Explanation:

The compounds X, Y and Z are borax, sodium metaborate + boric anhydride and boric acid respectively.

When borax is heated, it first swells and then forms a transparent glass like bead of sodium meta borate and boric anhydride.

BoraxNa2B4O7heatsodium metaborate2NaBO2+Boric anhydrideB2O3+10H2O

Aqueous solution of borax is alkaline due to formation of strong base NaOH.

Hence, it turns red litmus blue.

Na2B4O7+7H2O→4H3BO3+2NaOH

Borax reacts with sulphuric acid to form boric acid and sodium sulphate.
