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

Abstract

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
