The molal solubilities for nano zinc oxide ( ZnO ) in 2 MNH4Cl plus different percentages of dimethylformamide ( DMF ) and water solvents were measured at 294.15 K , 303.15 K , 309.15 K and 313 K .From the molalsolubilities for nanoZnO , the salvation parameters , activity coefficients, solubility products , free energies of solvation , transfer free energies for interaction , enthalpy of solution and entropy of solvation in 2 M NH4Cl plus mixed DMF – H2O solvents were evaluated . All these solvation parameters were discussed.
