WebAug 9, 2024 · \[\text{pH} + \text{pOH} = 14\nonumber \] The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7. The pOH is convenient to use when finding the hydroxide ion concentration from a solution with a known pH. Web=>pK w = pH + pOH = 14 The value of pK w controls the relative concentrations of hydrogen and hydroxyl ions as their product is always constant. pH of acids and bases can be roughly calculated with the help of pH scale while for accurate values we use pH meters. pH Example Chart pH Value and Nature of a Solution
