Question

The following salt undergoes hydrolysis:

• A. $KCI$
• B. $N{H}_{4}Cl$
• C. $NaCl$
• D. $K_{2}S{O}_4$

Answer 1

The correct option is B $N{H}_{4}Cl$

Salt of weak acid or weak base undergoes hydrolysis.
$N{H}_4^{+}$ will undergo hydrolysis as it is ion of weak base
$\therefore N{H}_{4}Cl$ will undergo hydrolysis

While other salt like $KCl$, $NaCl$ and $K_{2}S{O}_4$ are salt of strong acid and strong base thus will not undergoes hydrolysis.
