The current state of our understanding of ionic mobilities

Abstract

- As a result of extensive development of experimental techniques and equipment, highly precise limiting ionic conductances with their temperature and pressure dependences have been available for some time. This has resulted in several attempts to provide a theoretical basis to account for the deviations reported from Stokes’ behavior. These deviations in the conductance-visocsity product include a maximum in the ion size dependence, positive and negative temperature dependencies and different size dependencies for cations and anions as well as for large and small ions. Furthermore, specific solvent effects must be accounted for. In this article an attempt is made to evaluate several theories as to their ability to account for these deviations. © 1991, IUPAC
