Abstract
Dilute zinc solutions in the Zn−Pb−Cd system were investigated by an emf method with concentration cells to show the influence of variation in lead and cadmium concentrations on the zinc activity coefficients. Zinc concentrations were held in the mole fraction range 0.03≤X Zn≤0.1 with measurements in the temperature range 714<T<877°K. The interaction parameters, ∈ PbZn and ∈ ZnCd , were deduced from plots of (ln γZn) X Zn→0 vsX Pb. 3 The limiting values of zinc activity coefficients for other ternary systems previously investigated were analyzed using Krupkowski's method and the random solution model of Alcock and Richardson. Experimental data for ∈ 21 and ∈ 31 (where 1=Zn and 2, 3 are components of investigated ternaries) are compared also with the values obtained from limiting activity coefficients of the particular binary systems.
