neutral

acidic

alkaline

D

strongly acidic

Text Solution

Verified by Experts

The correct Answer is:
C
Borax is a salt of strong base `(NaOH)` and weak acid (boric acid). Therefore, in aqueous solution, it undergoes hydrolysis to give alkaline solution:
`Na_(2)B_(4)O_(7) + 7H_(2)O rarr 2NaOH + 4H_(3)BO_(3)` Therefore, borax is used as a water softener and cleansing agent.
