Abstract: The determination of the coefficients of kinematic viscosity for the ternary systems containing water, hydrochloric acid, and organic solvent (methyl alcohol, ethyl alcohol, and acetone) is described. This investigation concerns diffusion processes involving the ion exchange of chlorocomplexes of corrosion and fission products on anion exchangers. The values of viscosity coefficients have been determined and the validity of the relationship between the viscosity and composition of ternary systems has been tested. It has been found that the viscosity isotherms have convex shape with maxima at low concentrations of lrydrochloric acid (up to 1 м) for all three investigated organic solvents. At higher concentrations of hydrochloric acid in the ternary system, its viscosity increases with decreasing dielectric constant.
