State whether an aqueous solution of washing soda is acidic or alkaline.

Text Solution

Verified by Experts

An aqueous solution of washing soda is alkaline (turns red litmus blue). On dissolving in water, it forms NaOH (strong base) and chrbonic aid (weak acid).
`Na_(2)CO_(3)+2H_(2)tounderset(("strong base"))(2NaOH)+underset(("weak acid"))(H_(2)CO_(3))`
Therefore, resulting solution is alkaline or basic in nature.
