The electrical conductivity of [Ni(phen)‎3] Cl2 in methanol-water mixtures at 298 k

الملخص EN

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 4Wheaton equation for unsymmetrical electrolytes.

The conductivity parameters, ionic conductivity λ oNi2 +, association constant KA and the distance parameter R are calculated at the best fit values of the standard deviation σs (Λ).

The results indicate that λ o Ni2 + 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.
