Quizplus · Accepted Answer

When a weak acid is dissolved in water, it partially dissociates to form its conjugate base and H+. The equilibrium favors the left side of the equation, resulting in a low pH. However, when the salt of a weak acid is dissolved in water, the anion of the weak acid undergoes hydrolysis to form OH- ions, which raises the pH. The potassium salt of a weak acid has a higher pH compared to the weak acid, as potassium cation does not react with water.
