Abstract: The penetration of Na⁺ cations into anion exchanger Dowex 2X-8 was investigated in mixed solvent systems: ethyl alcohol—hydrochloric acid—water. The functional relations which describe the change in equilibrium distribution coefficients were determined for varying concentrations of macrocomponents in mixed solution. By the Gibbs —Donnan equation the values of the mean activity coefficient of sodium chloride were calculated for the inner solution of exchanger. The basic causes which control the penetration of cations into anion exchanger are discussed.
