| Abstract: | Differential pulse polarography was used to study the mixed ligand complexes of trimethylenediamine (TMDA) and oxalate (OX) with Cd(II) at constant ionic strength (μ = 1, NaNO3) at 25°C. It has been found that the reduction of complexes is reversible and diffusion-controlled. Three mixed complexes, Cd(TMDA)(OX)], Cd(TMDA)(OX)2]2? and Cd(TMDA)2(OX)], are formed. Their overall stability constants are: log β11 = 6.78, log β12 = 7.53 and log β21 = 8.20, respectively. |
