Dissociation constant of a weak acid is decreased by

A

Addition of a strong acid

B

Addition of a salt of the above weak acid

C

Decreasing temperature

D

Dilution of the solution

Text Solution

Verified by Experts

The correct Answer is:
C
Value of dissociation constant .K. of weak acid is constant at particular temperature. Hence, it decreases on decreasing the temperature and increases on increasing temperature.
