Assertion: The `pH` of `NH_(4)OH` remains unchanged on addition of `NH_(4)Cl`.
Reason : Addition of `NH_(4)Cl` suppresses the dissociation of `NH_(4)OH` due to common ion effect.

A

If both the assertion and reason are true and reason is the true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
The dissociation of `NH_(4)OH` is suppressed in presence of `NH_(4)Cl` and thus `pH` of `NH_(4)OH` decreases.
