Ion Pair Association Constant of Bis-1-Amidino-O-methylurea Copper(II) Acetate in Aqueous Medium at Different Temperature: A Conductance Study

摘要

Conductances of the bis-1 -amidino-O-methylurea copper(II) acetate has been measured in aqueous medium at 278.15 to 313.15 K. The conductance data in all the cases have been analyzed by Shedlovsky equation to obtain Λ_o, and K_A value for the electrolyte. The effect of temperature on the Stokes' radius for the complex cation has been discussed in the light of Walden product. Based on the K_A values and temperature dependence of Λ_o the thermodynamic parameters have been determined. The results have been discussed in terms of ion-ion and ion-solvent interactions.
