(A) is wrong. It forms acidic buffer and this pH changes (R) is correct. Due to common ion ( CH 3 COO ominus), ionization of CH 3 COOH is supressed

Q. Statement 1 : The pH of an aqueous solution of $C H_{3} COO H$ remains unchanged on the addition of $C H_{3} COON a$
Statement 2 : The ionization of $C H_{3} COO H$ is suppressed by the addition of $C H_{3} COON a$

Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1

Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1

Statement 1 is True, Statement 2 is False

Statement 1 is False, Statement 2 is True

(A) is wrong. It forms acidic buffer and this $p H$ changes
(R) is correct. Due to common ion $(C H_{3} CO O^{⊖})$ , ionization of $C H_{3} COO H$ is supressed
