Simultaneous elucidation of percentage composition & ionisation constants of acids by conductometric titration

Abstract

A new approach has been made to simultaneously elucidate percentage compositions and ionisation constants of acid, in a mixture by conductometric titration method. The angles of intersection of all the acids show a linear relation with the corresponding dissociation constant values. Polybasic acids, two- and three-component mixtures of acids have been tried with encouraging results. The method has been extended to medicinal compounds also. This simple nonmathematical approach may prove to be a useful technique for both qualitative and quantitative analysis of a compound having acidic properties.
