Ion Association Constants and Calculation of Thermodynamic Parameters of N-[(benzoyl-amino) thioxomethyl] Serine Copper (II) Chloride in Methanol + Water Mixed Solvents

Conductance values of a complex, N-[(benzoyl-amino) thioxomethyl] serine copper (II) chloride was estimated in methanol-water mixed solvents, viz.,  Xmethanol =0.0000 – 1.0000 at temperature ranges
283.15 to 313.15 K. From the experimental results, the ion association constants (KA) and limiting equivalent conductance (^0)  were determined by analyzing conductivity data concerning Shedlovsky
equations for the electrolytes. The Walden product, (^0Ƞ0) values were calculated in various water + + methanol mixtures at 283.15 to 313.15 K .It was observed that the increase in the percentage of values were calculated in various water methanol mixtures at to . It was observed that the increase in the percentage of methanol results in an increase in association constant values. It was also found that with the increase in KA values dielectric constant values were also increased. Increase in KA values with the increase in the dielectric constants of the mixtures. ^0  values linearly increased as the increased in temperature. Thermodynamic factors were calculated from the KAs and the results we got were examined.
