摘要： 298 15K条件下采用等压实验方法对与含氯化镉及氯化钾固态配合物平衡的五元水溶液体系(水+氯化钾+氯化镉+甘露醇+山梨醇)及其2个四元亚系(水+氯化钾+氯化镉+甘露醇)和(水+氯化钾+氯化镉+山梨醇)进行了热力学研究·以氯化钠水溶液为参考溶液,测定了不同水活度条件下该五元水溶液的渗透系数·实验结果表明,在误差允许范围内,上述五元系相对于其四元亚系的等压行为符合类理想溶液模型·

Abstract: Aimed at thermodynamic study, isopiestic experiments were carried out at 298.15 K for the quinary aqueous solution (water + potassium chloride + cadmium chloride + mannitol + sorbitol) and its two quaternary sub-systems (water + potassium chloride + cadmium chloride + mannitol) and (water + potassium chloride + cadmium chloride + sorbitol) to equilibrate them with a solid complex containing cadmium chloride and potassium chloride, with sodium chloride (aq) taken as reference solution to determine the osmotic coefficients of the quinary aqueous solution at different aqua activities. The results showed that the isopiestic behavior of the quinary system related to its quaternary sub-systems are well represented by the ideal-like solution model within permissible error range.
