Abstract
The formation and stability of some mixed Copper(II)-O-carboxylic liga nd complexes, has been studied by potentiometric measurements, at T = 25-degrees-C and I = 1 mol/1 (NaClO4). In both systems investigated (C u2+-acetate-malonate and Cu2+-acetate-succinate), the mixed species Cu (acetate)L (L=dicarboxylate ligand) was found. Particular attention ha s been paid to avoid bias in the calculation of stability constants. T he possibility of using these formation constants in the speciation pr oblem of multicomponent systems is discussed.
