A model Liouville equation is proposed for a system composed of an ion moving in a solvent fluid. Using this model, explicit results are obtained for the Ohmic conductivityL and the Hall conductivityh. These results are then used to calculate the Hall coefficientR = ehL–2, which is a measure of the effect of non-Brownian motion, for several charge carriers of interest. Our results are in agreement with earlier findings based on a stochastic model which predictR > 1 for H+(aq). Our results also indicate thatR 1 for charge carriers such as Na+, Cl–, and K+ which have a mass greater than that of a solvent molecule (here taken as 18 amu).
