Buffer action

Definition A buffer solution maintains an approximately constant pH, despite dilution or addition of small amounts of acid or base. Acidic buffer solutions contain a mixture of a weak acid (e.g. CH3COOH) and the salt of that weak acid (e.g. CH3COONa). Basic buffer solutions contain a mixture of a weak base (e.g. NH3(aq)) and the salt of that weak base (e.g. NH4Cl). Calculating the pH of a
