Thermodynamic properties of copper sulphate in urea + water mixtures from EMF measurements

Electromotive force measurements of the cell, Cu-Hg/CuSO 4(m), urea + water mixtures/Hg 2SO 4(s)/Hg have been done in four different compositions of urea + water mixtures at 303, 308, 313 and 318 K. These have been utilized to evaluate the standard potentials of the cell, the mean activity coefficie...

Description
Summary:Electromotive force measurements of the cell, Cu-Hg/CuSO 4(m), urea + water mixtures/Hg 2SO 4(s)/Hg have been done in four different compositions of urea + water mixtures at 303, 308, 313 and 318 K. These have been utilized to evaluate the standard potentials of the cell, the mean activity coefficient of copper sulphate (molal scale) and transfer energetics (Δ G 0 t, Δ S 0 t and Δ H 0 t) of copper sulphate from water to the respective urea + water mixtures (11.52, 20.31, 29.64 and 36.83 wt. % of urea). The transfer energetics have been explained in the light of ion-solvent interactions and structural contributions of solvents.
