Assertion (A): pH of neutral solution is...

Assertion (A): `pH` of neutral solution is always `7`.
Reason (R) : `pH` of solution does not depend upon temperature.

A

If both assertion and Reason are true and the Reason is the correct explanation of the assertion.

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
pH of a neutral solution is 7 at 298 K. on increasingg temperature, more water dissociates, consequently `[H^+]` increases, i.e., pH decreases.
