| Abstract The aim of this work is to measure the electrical conductivity of [Ni(Phen)3]Cl2 in different percentages of methanol-water mixtures at 298 K. The data were analyzed using Lee-Wheaton equation for unsymmetrical electrolytes. The conductivity parameters, ionic conductivity , association constant KA and the distance parameter R are calculated at the best fit values of the standard deviation s (). The results indicate that decrease on increasing percentage of methanol in the mixture. Maximum association obtained at equal percentage of H2O and methanol (50:50). The distance parameter was almost 29 A at each percentage forming solvent-separated ion pairs. Walden-product is also calculated for this system. | ||
