GUPTA (gupta_od@yahoo.com) 1 Department of Chemistry, University of Rajasthan, Jaipur-302055 (INDIA) <p style="text-align: justify;">A polarographic study of In(III) with Pentanedioic acid and 2-[(2-Aminoacetyl)amino] ethanoic acid in aqueous medium under varying temperatures at 300K and 310K have been carried out using KNO₃ as supporting electrolyte to maintain constant ionic strength (&micro; = 1M) TritonX-100 was used as maximum suppressor. The stability constants of In(III) with Pentanedioic acid and 2-[(2-Aminoacetyl) amino] ethanoic acid was evaluated first by DeFord and Hume&#39;s method while the stability constants of mixed complexes have been evaluated by the method of Schaap &amp; McMaster&#39;s. The reduction is found to be reversible and diffusion controlled involving three electrons in each case. The three species of mixed complexes MXY, MX₂Y, MXY₂ have been determined and found to be more stable than that of the simple ones. With the help of these data the statistical and electrostatic effects have been also studied.</p> https://journalofchemistry.org/paper/693/ Pentanedioic acid ethanoic acid simple and mixed ligand complexes polarographic study
