Answer
pH and pOH of any solution will always add up to 14 at room temperature. This is because, while pH measures the acidity of a solution, its counterpart pOH measures the alkalinity that is not accounted for by the pOH. Since the pH and pOH values of a neutral solution is 7, one can deduce that adding up the two quantities will yield 14.
