Formula and explanation
When a salt of a strong acid and a weak base (e.g., NH₄Cl ) dissolves in water, the weak base cation ( Mⁿ⁺ ) reacts with water, making the solution acidic. Hydrolysis ionic equation: Mⁿ⁺ + nH₂O ightleftharpoons M(OH) n + nH⁺. Simplified form (e.g., ammonium salts): NH₄⁺ + H₂O ightleftharpoons NH₃ · H₂O + H⁺. Hydrolysis constant K h = (K w)/(K b).
