Association Thermodynamic Parameters (Conductmetrically) for Nano Copper Sulfate in Mixed DMF–H2o Solvents at Different Temperatures

Mohamed N . H. Hamed

Abstract :

The molar conductance for nano copper sulfate (CuSO4) in different percentages of dimethylformamide (DMF) and water were measured at 292.15, 303.15, 308.15 and 313.15K. From the molar conductance for nano CuSO4 , the solvation parameters like, activity coefficient, association constant, free energy of assocation, enthalpy of association and entropy of association were estimated. All these solvation parameters were discussed.
