MCQ
What will happen when $\ce{CH_3COONa}$ is added to an aqueous solution of $\ce{CH_3COOH}$?
- AThe $pH$ of the solution decreases.
- ✓The $pH$ of the solution increases.
- CThe $pH$ of the solution remains unaltered.
- DAn acidic salt is produced.
✓
Answer
Correct option: B.
The $pH$ of the solution increases.
$\text{CH}_3\text{COOH}⇋\text{CH}_3\text{COO}^−+\text{H}^+$
If $\ce{CH_3COONa}$ is added, equilibrium will shift backward due to the common ion effect. $H^+$ will decrease.
