英文摘要	the simple equation relating the activity coefficient of each solute in mixed electrolyte solution to its value in binary solutions under isopiestic equilibrium was tested by comparison with the experimental data for the 18 electrolyte solutions consisting of 1:1, 1:2, and 1:3 electrolytes. the isopiestic measurements were made on the quaternary system bacl2-nh4br-nai-h2o and its ternary subsystems nai-nh4br-h2o, nai-bacl2-h2o, and nh4br-bacl2-h2o at 298.15k. the results were used to test the applicability of the zdanovskii's rule to the mixed electrolyte solutions which contain no common ions, and the agreement is excellent. the activity coefficients of the solutes in the above quaternary and ternary systems calculated from the above-mentioned simple equation are in good agreement with the pitzer's equation.
