Description
Summary:The absolute rate theory of viscosity for simple fluids has recently been extended to account for the concentration dependence of the viscosity of concentrated single electrolyte solutions at a fixed temperature. This new approach has been further developed in this paper to derive equations which account for the viscosity of mixtures of concentrated electrolyte solutions. A comparison of these equations with the simple additive equations which have been previously postulated to account for the viscosity of salt solution mixtures has revealed that the former equations give agreement with observed data to within 1% whereas the latter equations yield errors ranging from 5 to 20%.
