Abstract

Mathematical modelling of a multi-component titration system of hydrolytic titrations of metal ions is described. A comparison of the calculated and experimental titration curves and end volumes in the Ca2+ -F_ system at different pH values of titrated solutions is presented. The determination of the end-point of titrations by several approximation and mathematical methods is described.
