`pOH` of `H_(2)O` is `7.0` at `298K`. If water is heated at `350 K`, which of the following statement should be true?

A

`pOH` will decrease

B

`pOH` will increases

C

`pOH `will remain `7`.

D

Both (A) and (B)

Text Solution

Verified by Experts

`[OH^(-)]=sqrt(K_(W))` in pure water. so as temperature `K_(w)` increase rArr `[OH^(-)]` increases rArr `pOH` decreases
