Q. Statement 1 : The pH of an aqueous solution of $CH _3 COOH$ remains unchanged on the addition of $CH _3 COONa$
Statement 2 : The ionization of $CH _3 COOH$ is suppressed by the addition of $CH _3 COONa$

Equilibrium

Solution:

(A) is wrong. It forms acidic buffer and this $pH$ changes
(R) is correct. Due to common ion $\left( CH _3 COO ^{\ominus}\right)$, ionization of $CH _3 COOH$ is supressed
