pH is a notion that expresses the concentration of hydrogen in a solution while pOH expresses the concentration of hydroxide in a solution. The sum of pH and pOH in a solution is 14.

Answer: 14

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.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

[tex]pH=-\log [H^+][/tex]

[tex]pOH=-\log[OH^-][/tex]

[tex]pH+pOH=14[/tex]

Thus the sum of pH and pOH is 14.
