On diluting a buffer solution, its `pH`

A

Increases

B

Decreases

C

Remains same

D

Cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
C
On dilution, the concentration of both salt and acid decreases, so the `(["Salt"])/(["Acid"])` remains same and `pH` does not change.
