Abstract
In biological systems transition metal ions exists in the form of different metal ligand complexes therefore investigations on the stability of metal complexes in relation with various structural features are important. Such type of study will help for understanding the driving forces leading to the formation of such complexes in the biological systems. Here we have reported systematic potentiometric studies on the formation of metal ligand complexes of transition metal ions with 2, 2- bipyridyl ligand in aqueous solution at 27 0 C temperature in the presence of electrolyte 1N NaNO3. The protonation constant and metal ligand stability constants were determined using Irving Rossotti titration technique. Data obtained from titrations were analysed by SCOGS computer programs. The protonation constant values obtained by half integral method and point wise method are in agreement.
