摘要/Abstract

摘要：利用铜电极和Ag-AgCl电极组成可逆电池,通过测定电池的电动势,应用Nernst方程和Debye-Hückel公式,求得不同温度下CuCl₂在混合溶剂(DMF-H₂O)中的平均离子活度系数,计算CuCl₂在混合溶剂中的相对偏摩尔自由能,并根据电解质溶液的溶剂化理论，对CuCl₂的平均离子活度系数及相对偏摩尔自由能的变化规律进行了讨论.

关键词： 活度系数, 相对偏摩尔自由能, 混合溶剂, 电池电动势, DMF(N,N-二甲基甲酰胺), CuCl₂

Abstract: The reversible cell discussed in this paper consists of the copper electrode and the Ag-AgCl electrode.By the Nernst formula and the limited formula of Debye-Hückel,the measured the activity coefficients and the relative partial molar free energies of copper chloride in H₂O-DMF mixed solvent at different experimental temperatures were calculated.The behaviors of change of the activity coefficients and the relative partial molar properties of copper chloride in H₂O-DMF mixed solvent are discussed on the basis of theory of electrolytic solution.

Key words: activity coefficient, relative partial molar free energies, mixed solvent, electrode potential, DMF(N,N-dimethylformamide), CuCl₂ (copper chloride)
