Solution

The correct option is B False
$N H_{4} C l$ when dissolved in water undergoes cationic hydrolysis as follows:
$N H_{4} C l$ $\to$ $N H_{4}^{+} + C l^{-}$
Ammonium ion being a strong acid takes $O H^{-}$ ions furnished by water as :
$N H_{4}^{+} + H_{2} O \to N H_{4} O H (f r e e l y i o n i z e d) + H^{+}$
Thus concentration of $O H^{-}$ ions decreases and that of $H^{+}$ ion increases due to cationic hydrolysis and consequently the solution become acidic in nature.
