Chemistry

Thus hydroxide ion concentration is $10^{-11}M$

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 and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

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

$pOH=-log{OH^-}$

pH+pOH=14

Given: pH=3

3+pOH=14

pOH=11

11=-log[OH^-]

$[OH^-]=10^{-11}$

Thus hydroxide ion concentration is $10^{-11}M$
