ABSTRACT:

The polarographic determination of stability constants of metal complexes of Thallium(I) with Ornithine monohydrogen chloride under varying temperatures 300K and 313K in aqueous media have shown the formation of 1:1, 1:2 and 1:3 complexes. The values of overall stability constants of complexes have been calculated by DeFord and Hume’s method which is further verified by Mihailov’s method. The reduction process was found to be reversible and diffusion controlled. The change in thermodynamic parameters DG°, DH° and DS° accompanying complexation have been also evaluated.
