Abstract :

The molar solubility for nano copper carbonate (CuCO3) in different percentages of dimethyl formamide (DMF) and water were measured at 292.15, 303.15, 308.15 and 313.15 K. From the molar solubilities for nano CuCO3, the solvation parameters like, activity coefficient, solubility product, free energy of solvation, enthalpy of solvation and entropy of solvation were estimated. All these solvation parameters were discussed.
