Answer:

The correct answer is option b.

Explanation:

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

The ionic product of water : $K_w$

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

A pure water has equal concentration of hydrogen ions and hydroxide ions, hence neutral.

$K_w=[H^+][H^+]=[H^+]^2$

The ionic product of water at 283 K = $K_w=0.29\times 10^{-14}$

$K_w=[H^+]^2$

$0.29\times 10^{-14}=[H^+]^2$

$[H^+]=5.385\times 10^{-8} M$

The pH of the water at 283 k;

$pH=-\log [H^+]$

$=-\log[5.385\times 10^{-8} M]=7.26$

A pure water has equal concentration of hydrogen ions and hydroxide ions,So water will e neutral at this temperature also.

The correct answer is option b.
