Polarographic studies on the Cu(II) complex of SALH2.NaNO3.H2O* (I): determination of the standard free energy of activation and the integral heat of solution
Ali Rıza Özkaya
In this work, polarographic reduction of the Cu(II) complex of schiff base ligand SALH2. NaNO3. H2O was investigated in the solvent media of aqueous 70% Dimethylsulfoxide (DMSO). The reduction of the complex was found to take place in two electrochemical steps indicated by two well - defined polarographic waves. While the first wave involved a two - electron irreversible process, the second wave indicated a one - electron irreversible wave. Also the integral heat of solution ΔHs, of the complex in aqueous 70% DMSO and th standard free energy of activation, ΔG°≠, for each electrode process have been determined by using the polarographic data.
