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

الملخص EN

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, Λo (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 (Λ oη ) found to be not constant for the three media which describe as to the change of ion-solvation and of the solvent structure.
