Answer: The concentration of hydrogen ions is [tex]10^{-11}M[/tex] and the concentration of hydroxide ions is [tex]10^{-3}M[/tex]. 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.
[tex]pH=-\log [H^+][/tex]
[tex]pOH=-\log[OH^-][/tex]
Putting in the values:
[tex]11=-\log[H^+][/tex]
[tex][H^+]=10^{-11}M[/tex]
[tex]pH+pOH=14[/tex]
[tex]pOH=14-11=3[/tex]
[tex]3=-log[OH^-][/tex]
[tex][OH^-]=10^{-3}M[/tex]
Thus the concentration of hydroxide ions is more than the concentration of hydrogen ions.
