 in Mixed DMF–H2O Solvents at Different Temperatures&description=The molal solubility for nano and bulk (normal) lead bromide (LBr) in different percentages of dimethylformamide (DMF) and water were measured at 298.15, 303.15, 308.15 and 313.15K. From the molar solubilities for nano and bulk (LBr), 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 and compared for both nano and bulk (LBr).&picture=http://www.aascit.org/aascit/decorators/img/journal/916.jpg)
