Abstract

With the use of a microscopic velocity field and some hydrodynamic approximations a generalized Stokes-Einstein (GSE) relation among the self-diffusion constant Ds, the viscosity η, and the electric conductivity σe is derived for ionic binary mixtures. Our approach, when applied to nonionic binary mixtures of arbitrary molar fraction, gives a GSE relation among Ds, η, and the interdiffusion constant DAB. The self-diffusion constant is calculated from the GSE relation for molten salts and some organic binary mixtures and the results are compared with the experimental ones.
