Conductivity Study of Tetra Aqua -1,10- Phenanthroline Zinc(II) Chloride in Aqueous Methanol Mixture at Different Temperatures

Abstract

The electrical behavior of association phenomena of tetra aqua (1,10 _ phenanthroline) zinc(II) chloride in methanol-water mixture have been investigated by precise conductance measurements at 288.15-308.15K which can give informations about ion-ion and ionsolvent interactions in solution. The limiting molar conductance λ M 2+ , the association constant K A and R the main distance between ions in solution as a results of those interactions can be calculated. Thermodynamics parameters (∆H, ∆G, ∆S) of the association processes and the coulombic forces which play an important role in the association process have been studied also.
