This paper presents a new model for correlating kinematic viscosity of binary strong electrolyte solutions. The new model, based upon Eyring theory, considers that molecular interactions among anion, cation, and molecule occur in a certain way. The new equation correlates the viscosity of different aqueous electrolyte solutions within an absolute percentage error of 0.49% with a standard deviation of 0.4%. Comparison to existing correlations also appears in this work.
