| Abstract | ||
| Electrolytic conductivities of mixed ligand complex of Ni(II) in binary mixtures of methanol and water have been measured at 288.15-308.15 K. The limiting molar conductances (o) and the ion association constants (KA) of the electrolytes have been evaluated by analysis of the conductance data using the Lee and Wheaton conductivity equation. Thermodynamics of the association processes have also been studied and the coulombic forces are found to play a major role in the association processes. Walden product (oo) have also been calculated for each solvent composition. A linear relationship was found to exist between the logarithm of the association constant (log KA) and the reciproced of the dielectric constant (1/D) of the medium which indicate the tendency of the association of ions. | ||
