The values of overall stability constants of complexes have been calculated by DeFord and Hume&#39;s method which is further verified by Mihailov&#39;s method. The reduction process was found to be reversible and diffusion controlled involving three electron transfer. The change in thermodynamic parameters DG&deg;, DH&deg;, and DS&deg; accompanying complexation have been also evaluated. It was found that the stability constants of In(III)-2,2&acute;-Oxydiacetic acid system in aqueous non-aqueous medium are greater than in aqueous medium.<br /> <em>Ke words :</em> Electrochemical, polarography, dropping mercury electrode, effect of temperature, 2,2&acute;-Oxydiacetic acid, In(III), Mihailov&#39;s method and DeFord and Hume&#39;s method.</p> </td> </tr> <tr> <td> <p>&nbsp;</p> </td> </tr> </tbody> </table> https://journalofchemistry.org/paper/724/ Electrochemical polarography dropping mercury electrode effect of temperature
