Vedclass · Answer

(A) $(i)$ Sodium acetate $(CH_3COONa)$ is a salt of a weak acid $(CH_3COOH)$ and a strong base $(NaOH)$. When dissolved in water, it undergoes hydrolysis to form a basic solution:$CH_3COO^- + H_2O \rightleftharpoons CH_3COOH + OH^-$Since the solution is basic, the $pH > 7$.$(ii)$ Ammonium chloride $(NH_4Cl)$ is a salt of a strong acid $(HCl)$ and a weak base $(NH_4OH)$. When dissolved in water, it undergoes hydrolysis to form an acidic solution:$NH_4^+ + H_2O \rightleftharpoons NH_3 + H_3O^+$Since the solution is acidic, the $pH Therefore, the correct option is $(i)$ $pH > 7$ and $(ii)$ $pH < 7$.

The $pH$ of the solution, when
$(i)$ sodium acetate is dissolved in water.
$(ii)$ ammonium chloride is dissolved in water.
