pH of water is 7.0 at `25^(@)C`. If water is heated to `80^(@)C`

A

pH will increase

B

pH will decrease

C

pH remains 7.0

D

`H^(+)` ion concentration will increase but `OH^(-)` ion concentration will decrease

Text Solution

Verified by Experts

The correct Answer is:
B
pH of water is 7 at `25^(@)C` as temp . Increase ionic product of water increase so pH decreases .
