R3.1 (AHL) Salt hydrolysis, pH titration curves and indicators
This AHL section explains why the pH of a salt (i.e. whether it is neutral, acidic or basic in aqueous solution) depends on the relative strengths of the parent acid and base. The characteristic shapes and features of pH curves for different combinations of strong and weak monoprotic acids and bases are covered and the mechanism and choice of an appropriate indicator for titrations involving each particular...
