`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?

Options

A. `pOH` will decrease
B. `pOH` will increases
C. `pOH `will remain `7`.
D. Both (A) and (B)

Explanation

To solve the problem regarding the change in pOH of water when it is heated from 298 K to 350 K, we can follow these steps:

### Step 1: Understand the concept of Kw
Kw, the ionic product of water, is defined as:
\[ K_w = [H^+][OH^-] \]
At 298 K, the value of Kw is \( 1.0 \times 10^{-14} \).

### Step 2: Recognize the effect of temperature on Kw
