Q. $NH_{4}Cl$ is acidic because
A) On hydrolysis $NH_{4}Cl$ gives weak base $NH_{4}OH$ and strong acid $HCl$
B) Nitrogen donates a pair of electrons
C) It is a salt of weak acid and strong base
D) On hydrolysis $NH_{4}Cl$ gives strong base and weak acid
Explanation
(a)
$NH_{4}Cl$ is acidic because it is a salt of weak base $NH_{4}OH\ and\ a\ strong\ acid\ HCl$. Thus, on hydrolysis, it gives strong acid $HCl\$and weak base$\ NH_{4}OH$.
$NH_{4}Cl + H_{2}O \rightarrow NH_{4}OH + HCl$
