Abstract

Standard molar Gibbs free energies, enthalpies, and entropies of transfer between solvents have been reported by many authors for a large number of cations (mainly uni- and divalent) and anions (univalent). These quantities could be related to properties of the ions and the solvents, permiting predictions of such quantities. Also the transfer Gibbs free energies of divalent anions (sulfate and others) predicted on this basis agree with reported values. Only recently have the author and coworkers been able to extend this approach to the partial molar volumes and heat capacities of ions in various non-aqueous solvents using a multivariate statistical treatment, based, however, on a much more modest database. For these structure-related quatities the electrical properties of the solvents (permittivities, dipole moments) are not relevant, whereas their hydrogen bonding abilities are.
