Question

An aqueous solution of ${\mathrm{CH}}_3\mathrm{COONa}$ is ____________.

Answer 1

Sodium acetate $\left({\mathrm{CH}}_3\mathrm{COONa}\right)$

• ${\mathrm{CH}}_3\mathrm{COONa}$ is a salt of a strong base $\left(\mathrm{NaOH}\right)$and weak acid$\left({\mathrm{CH}}_3\mathrm{COOH}\right)$.
• The dissociation of ${\mathrm{CH}}_3\mathrm{COONa}$ is as follows:-
• ${\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{aq}\right)\to {\mathrm{CH}}_3{\mathrm{COO}}^{-}+{\mathrm{Na}}^{+}$

The reaction of ${\mathrm{CH}}_3{\mathrm{COO}}^{-}$ with water

• The reaction of ${\mathrm{CH}}_3{\mathrm{COO}}^{-}$ with water is as follows:-
• ${\mathrm{CH}}_3{\mathrm{COO}}^{-}+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{OH}}^{-}$
• Due to the formation of ${\text{OH}}^{-}$, an aqueous solution of ${\mathrm{CH}}_3\mathrm{COONa}$ is basic in nature.

So, an aqueous solution of${\mathrm{CH}}_3\mathrm{COONa}$ is basic.
