Electrical Conductivity of [Co(en)2Cl2] Cl in Mixed Solvents (Alcohol + Water) at 298K

The electrical conductivity of trans dichloro bis(ethylenediamine) cobalt (III) chloride [Co(en)2Cl2] Cl has been measured in (methanol + water), (ethanol + water) and (isoproponal + water) at different percentages and at 298K. The conductivity parameter, o (equivalent conductivity at infinite dilution, Ka; (association constant) and R the (distance parameter) between the ions were calculated by using Lee Wheaton equation for symmetrical electrolytes.
The Walden product ( ) found to be not constant for the three media which describe as to the change of ion-solvation and of the solvent structure.
