Question

Aqueous solution of ammonium chloride $\left(N{H}_{4}Cl\right)$ is :

• A. Acidic due to cationic hydrolysis.
• B. Basic due to anionic hydrolysis.
• C. Neutral.
• D. Hydrolysis of both cation and anion occur.

Answer 1

The correct option is A Acidic due to cationic hydrolysis.

$N{H}_{4}Cl$ is a salt of strong acid $HCl$ and weak base $N{H}_{4}OH$
Hydrolysis :
$N{H}_4^{+}\left(aq\right)+H_{2}O\left(l\right)\rightleftharpoons N{H}_{4}OH\left(aq\right)+H^{+}\left(aq\right)$
Note :-
Only the cation will undergo hydrolysis and the solution will be acidic in nature due to $H^{+}$ formation.So here, the cation is responsible for the acidic nature of the solution
In this case $pH<7$
