Chemistry Question on Acids and Bases

: pHpH of neutral solution is always 77. : pHpH of a 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

Answer

If both Assertion: and Reason: are false

Explanation

Solution

pHpH of a neutral solution is 77 at 298K298\, K increasing temperature, more water dissociates, consequently [H+][H^+ ] increases, i.e. pHpH decreases.
