Explain state as why the solution of `Na_(2)CO_(3)` is alkaline ?

Text Solution

Verified by Experts

`Na_(2)CO_(3)` is a salt of `H_(2)CO_(3)` and NaOH i.e., , a weak acid `(H_(2)CO_(3))` and a strong base `(NaOH)`. So it undergoes hydrolysis to produce strong base, NaOH and hence, its aqueous solution is alkaline in nature.
`Na_(2)CO_(3)(s)+H_(2)O(l) to underset(("strong base"))(2NaOH(aq))+underset(("weak acid"))(H_(2)CO_(3)(aq))`
