The Ph OF NEUTRAL WATER AT 25^(@)C is 7....

The Ph OF NEUTRAL WATER AT `25^(@)C` is `7.0.` As the temperature increases, ionisation of water increases, however the concentration of `H^(+)` ions nad `OH^(-)` ions equal. What will be the ph of puire water at `60^(@)C`?

A

Equal to 7.0

B

Greater than 7.0

C

Less than 7.0

D

Equal to zero

Text Solution

Verified by Experts

The correct Answer is:
C
Since ionisation of water increases upon increasing the temperature, `[H^(+)]` increases. The ph of the solution therefore, decreases and beocomes less than 7.
