The present electrochemical study deals with the evaluation of a complexation process involving different metal and ligands and its physicochemical properties to find out the ligand- metal ratio of complex in solution. For the determination of complexing nature “Monovariation method” have been used to ascertain the ligand metal ratio in the complex. The stability constant of the formed complexes were calculated by conductance measurement using Modified Job’s method (Turner Anderson Method). The analysis had been carried out by using conductometric principle and the final outcome of the experiment may influenced by temperature and with the ionic concentration of metal and ligand solution. Free energy change values were determined to find out the feasibility of the complexation process. One of the method was validated statistically by using system and method precision parameters. Lastly the complexes was been assayed by using a specific chromogenic agent with a specific spectroscopic technique that may give biological action in future.
