%X Abtract New equation was applied for the Calculation of association constant (KA) from the reaction of Cu(NO3)2 with Kryptofix-221 in mixed (MeOH-DMF) and in absence and Presence of ligand at different temperatures. From the experimental results, the molar conductance (¦«) were evaluated. The limiting molar conductance (¦«¦Ï) were also estimated. Gibbs free energies of association (¦¤GA) was also estimated, Moreover, recalculation of (KA) was achieved by applying Shedlovsky and Fouss-Kraus extrapolation methods. In addition, the molar solvated (V), Van der Waals (VW), electrostriction (Ve) and apparent molar ( v) volmes were calculated. Also, the enthalpy change (¦¤H) and the entropy change (T¦¤S) for Cu(NO3)2 were calculated. The degree of dissociation (¦Á) were also calculated. All the results were discussed in view of ion-solvent interactions.
