Abstract

The solubilities of five 1:1 electrolytes in 1,1,3,3-tetramethylurea (TMU)-water mixtures have been determined. Combination of these data and ion pair association for the electrolytes in TMU-water mixtures yield solubility (ion-activity) products from which free energies of solution of the ionic species M+ + X- have been calculated. Using the corresponding data in water, the free energies of transfer of M+ + Y- from water to TMU-water mixtures are obtained. The changes in free energy that accompany the transfer of electrolytes from water to mixed aqueous solvents will be discussed.
