Formula and explanation
When a salt of a weak acid and a strong base (e.g., NaAc ) dissolves in water, the weak acid anion ( A⁻ ) reacts with water, making the solution basic. Hydrolysis ionic equation: A⁻ + H₂O ightleftharpoons HA + OH⁻. Hydrolysis constant K h = (K w)/(K a), where K w is the ion product of water and K a is the acid dissociation constant of the weak acid.
