`pOH` water is `7.0at 298 K`. If water is heated to `350K`, which of the following should be ture?

A

pOH will decrease

B

pOH will increase

C

pOH will remain 7.0

D

Concentration of `H^+` ions will increase but that of `OH^-` will decrease

Text Solution

Verified by Experts

The correct Answer is:
A

On heating water, its degree of ionization increases producing larger concentration of `H_3O^+` and `OH^-` ions. Therefore ,pOH will decrease .
