Vedclass · Answer

(C) salt formed from a strong base and a weak acid undergoes anionic hydrolysis to form a basic solution. $KCN$ is a salt of a strong base $(KOH)$ and a weak acid $(HCN)$. When dissolved in water,the $CN^-$ ion reacts with water: $CN^- + H_2O \rightleftharpoons HCN + OH^-$. The production of $OH^-$ ions makes the solution basic. $NaNO_3$ is a salt of a strong acid and a strong base (neutral). $CH_3COONH_4$ is a salt of a weak acid and a weak base (nearly neutral). $NH_4F$ is a salt of a weak base and a weak acid (nearly neutral).

Which among the following salts forms a basic solution when dissolved in water?
