In a mixture of weak acid and its salt, the ratio of concentration of salt to acid is increased ten fold. The pH of the solution

The rapid change of pH near the stoichiometric point of an acid-base titration is the basic of indicator detection. pH of the solution is related to the ratio of the concentration of conjugate acid (Hin) and base (In^(-)) forms of the indicator by the expression
