ABSTRACT:

Equilibrium studies on mixed ligand and mixed metal systems of biological relevance is the most fascinating area of research for inorganic chemists. This can be attributed to the interesting results generated from such studies. Present paper deals with the pH-metric equilibrium investigation on Ni(II)-DOPM-ala/phe/asp/glu ternary systems. The systems were investigated keeping the metal and ligands in equimolar ratio at three different ionic strengths (i.e. 0.05M, 0.10M and 0.15M (NaNO3)) at 20±1

KEYWORDS:

Equilibrium studies; Ternary systems; Formation constant
