Assertion : The pH of an aqueous solution of acetic acid remains unchanged on addition of sodium acetate.
Reason : The ionization of acetic acid is increased by addition of sodium acetate.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but(R) is not the correct explanation of (A)

C

If(A) is correct, but (R) is incorrect

D

If both (A) and (R) are incorrect

Text Solution

Verified by Experts

The correct Answer is:
D
Due to common iọn effect, it suppresses the ionization of`CH_(3) COOH` which decréases `[H^(+)]` and hence pH value increases.
