The proton-ligand stability constants and metal-ligand stability constants of 2-Amino-5-Chloro Benzene Sulphonic Acid and its complexes with Cu (II) metal ions were investigated at different ionic strengths pH-metrically and the data were utilized to estimate the thermodynamic stability constants at zero ionic strength and to know the exact nature of the complexation equilibria. The different possible reactions and expected values of DZ2 for corresponding dissociation or association equilibria are determined.
