The concentration of hydrogen ions is $10^{-11}M$ and the concentration of hydroxide ions is $10^{-3}M$ . Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

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

$pOH=-\log[OH^-]$

Putting in the values:

$11=-\log[H^+]$

$[H^+]=10^{-11}M$

pH+pOH=14

pOH=14-11=3

3=-log[OH^-]

$[OH^-]=10^{-3}M$

Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
