$[OH^-]^2=2.0\times 10^{6}$

Explanation:

The ionization constant of the water = $4.0\times 10^{12}$ at a temperature of $112\ ^0C$ and pressure of 20 MPa

Water dissociates as;

$H_2O\rightleftharpoons H^++OH^-$

The expression for the ionization constant is :

K_w=[H^+][OH^-]

For pure water,

[H^+]=[OH^-]

So,

K_w=[OH^-]^2

$[OH^-]^2=4.0\times 10^{12}$

The concentration of the hydroxide ions, $[OH^-]^2=2.0\times 10^{6}$ .
