Coulometric titration in the study of metal ion-ligand equilibria.
The coulometric titration technique is applied to evaluation of stability constants of metal complexes with ligands which have protolytic properties. The validity of the procedure was checked by studying several well-known systems. The proposed method can be used with success when metal ions are not reduced at the working cathode. Constants for calcium and magnesium complexes with components of some biologically important buffers, so-called Good buffers, were evaluated under experimental conditions (ionic strength of 0.16M, 37 degrees ) used in clinical analysis.
