本文给出了298.15 K时11种锌、镉和亚乙基双（三甲基铵）氯化物和碘化物的二价化合物在水溶液中的平均活度和渗透系数的临界值。渗透系数计算直接蒸汽压测量，等压测量和冰点下降测量。活度系数计算从电动势测量原电池有和没有转移。给出的是三个不同的相关方程的经验系数，通过加权最小二乘拟合的实验数据，和表组成的化合物的活性系数，渗透系数和活性的水，和溶液的过量吉布斯能作为每种电解质系统的重量摩尔浓度的函数。文献覆盖面是通过1979年9月的计算机化版本的化学文摘。
A critical evaluation of the mean activity and osmotic coefficients in aqueous solutions of eleven bi‐univalent compounds of zinc and cadmium and ethylene bis(trimethylammonium) chloride and iodide at 298.15 K is presented. Osmotic coefficients were calculated from direct vapor pressure measurements, from isopiestic measurements and from freezing point depression measurements. Activity coefficients were calculated from electromotive force measurements on galvanic cells with and without transference. Given are empirical coefficients for three different correlating equations, obtained by a weighted least squares fit of the experimental data, and tables consisting of the activity coefficients of the compounds, the osmotic coefficients and activity of water, and the excess Gibbs energy of the solution as functions of the molality for each electrolyte system. The literature coverage is through the computerized version of Chemical Abstracts of September 1979.
