Abstract

Study of Complex Formation between Itaconic Acid and Cd(II) Ion in Aqueous and Non-Aqueous Solvents (40% DMF, 40% DMSO, 40% Ethanol) using Polarographic Technique (DME)

Author(s): Chanchal Karadia and O. D. Gupta

Studies of Cd (II) complexes with itaconic acid have been carried out by polarographic method in aqueous and non-aqueous media (40% DMSO, 40% DMF, 40% Ethanol) under varying temperatures, at 298 K and 308 K in presence of KCl as a supporting electrolyte. The reduction of Cd (II) was found to be reversible in aqueous and non-aqueous medium for itaconic acid ligand and have shown the formation of 1 : 1, 1 : 2, and 1 : 3 complexes. DeFord and Hume’s method as modified by Irving has been applied for the determination of composition and stability constant of the complexes species. The changes in thermodynamic parameters ∆H°, ∆G° and ∆S° accompanying complexation have been evaluated. The mathematical Mihailov’s method has also been applied for the comparison of stability constants values.
