The concentration of hydroxide ions at this temperature is $7.16\times 10^{-7}$

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

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

$5.13\times 10^{-13}=[H^+][OH^-]$

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

$5.13\times 10^{-13}=x^2$

$x=7.16\times 10^{-7}$

The concentration of hydroxide ions at this temperature is $7.16\times 10^{-7}$
