To study the metal-ligand equilibrium in aqueous solution, the well known Irving-Rossotti titration method was used. The temperature selected is 25 ± 0.50C at ionic strength 1M (NaClO4) which was maintained constant throughout the complexation.
The binary metal-complex (ML2) formation was studied. The metals selected as Cr with benzoic acid, p-chloro benzoic acid, p-nitro benzoic acid, p-amino benzoic acid as ligands. Factors which affects the stability constant are size, basicity of ligand and steric effect of ligands.
