Question

Ammonium chloride undergoes dissociation to produce ______ and _____ ions.

• A. $N{H}_4^{+}$ and $C{l}^{-}$ respectively
• B. $N{H}_3^{+}$ and $C{l}^{-}$ respectively
• C. $A{l}_3^{+}$ and $C{l}^{-}$ respectively
• D. $N{H}_2^{+}$ and $C{l}^{-}$ respectively

Answer 1

The correct option is A

$N{H}_4^{+}$ and $C{l}^{-}$ respectively

Ammonium chloride $\left({\text{NH}}_4\text{Cl}\right)$ is an acidic compound which on dissolving with water undergoes dissociation to form ${\text{NH}}_4^{+}$ and ${\text{Cl}}^{-}$ ions. Individual charges of cation and anion are +1 and -1 respectively. The reaction involved is:

${\text{NH}}_4\text{Cl}\text{(aq)}\leftrightharpoons {\text{NH}}_4^{+}\text{(aq)}+{\text{Cl}}^{-}\text{(aq)}$
