Conductivity study of tetra aqua-1, 10-phenanthroline cobalt (II)‎ chloride [Co (1, 10-phen)‎ (H2O)‎4] Cl2 in methanol-water mixture at different temperatures

الملخص EN

The hydrodynamic behaviour of tetra aquo-1,10-phenanthroline cobalt (II) chloride in methanol-water mixture have been investigated by precise conductance measurements at 288.15-308.15 K.

The limiting molar conductances (Λo), ion association constant KA of the electrolyte and the main distance between ion in solution (R) have been evaluated by Lee- Wheaton conductivity equation.

Coulombic forces are found to play a major role in the association processes from thermodynamic point of view.

Walden products (Λoηo) have also been calculated for each solvent composition.
