For the given titration curve of a weak base with a strong acid, The pH and the added volume of the base at the equivalence point is to be determined. The volume of the added acid is to be determined at which the volume of added acid is the pH calculated by working an equilibrium problem based on the initial concentration and K a of the weak acid. The volume of added acid at which p H = 14 − p K b is to be determined. The volume of the added acid is to be determined at which the volume of added acid is the pH calculated by working an equilibrium problem based on the initial concentration and K a of the conjugate acid. The volume of added acid is to be determined beyond which the volume of added acid is the pH calculated by concentrating on the amount of excess added strong acid.
