Question

${\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to {\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{aq}\right)+H_{2}O\left(l\right)$
The pH of the resultant solution will be .

• A. acidic
• B. neutral
• C. alkaline

Answer 1

The correct option is C alkaline

Acetic acid (${\text{CH}}_3\text{COOH}$) is a weak acid which on interaction with a strong base ($\text{NaOH}$) undergoes partial neutralisation reaction. The salt formed as a result is alkaline/basic in nature. Hence, the solution is alkaline (pH > 7).
Weak acid + Strong base $\to$ Alkaline/Basic salt + Water
