Overall stability constants of mixed ligand complexes formed by Pb(II) with ethylenediamine-malonate and propylenediamine-malonate have been determined. The reductions were reversible and diffusion-controlled involving two electrons in both systems. The equilibrium concentration of the ligand is calculated from pH and the total amount present using pK values. The formation constants have been used to discuss the results.
