$NH_4Cl$

Vedclass · Answer

(C) Cationic hydrolysis occurs in salts of a weak base and a strong acid. In $NH_4Cl$,the salt dissociates as: $NH_4Cl \rightarrow NH_4^{+} + Cl^{-}$. $Cl^{-}$ is the conjugate base of a strong acid $(HCl)$ and does not undergo hydrolysis. $NH_4^{+}$ is the conjugate acid of a weak base $(NH_3)$ and undergoes hydrolysis: $NH_4^{+} + H_2O \rightleftharpoons NH_3 + H_3O^{+}$. Thus,only cationic hydrolysis is involved.

In which of the following salts,only cationic hydrolysis is involved?
