Weak complexes of sulphur and selenium: a thermodynamic view on solvent effects in mixed solvents

Abstract

The effect of mixed solvent on complex stability is discussed from a thermodynamic standpoint. The variation in the free energy of formation for a complex species in different solvent mixtures is an indication of solvent-solute and solvent-solvent interactions. The complexity of the systems in mixed solvents makes entropy data difficult to interpret. Evidence is given on solvent-solvent interactions. © 1982.
