Abstract:
Isopiestic measurements have been carried out at 298.15 K for the quaternary aqueous solution H2O+KCl(sat)+NaCl+NH4Cl saturated with potassium chloride and its ternary sub systems H2O+KCl (sat)+NaCl and H2O+KCl(sat)+NH4Cl. Taking sodium chloride (aq) or calcium chloride (aq) as reference solutions, osm otic coefficients and water activities of the aqueous solution were determined. The experiment results show that the isopiestic actions of the quaternary system related to its ternary sub-systems are in excellent agreement with the ideal like solution model.

摘要:
在298.15 K 条件下采用等压实验方法对KCl饱和的四元水溶液体系H2O+KCl(饱和)+NaCl+NH4Cl及其两个三元亚系H2O+KCl(饱和)+NaCl和H2O+KCl(饱和)+NH4Cl进行了研究.以NaCl或CaCl2水溶液为参考溶液,测定了不同水活度条件下该四元水溶液的渗透系数及水活度.实验结果表明,该四元系与其两个三元亚系之间存在着简单的共性,在实验误差允许范围之内,该四元系的等压行为符合类理想溶液模型.
