摘要: 用等压法测量了苯亚磺酸钠、苯磺酸钠、对羟基苯磺酸钠、间硝基苯磺酸钠和对氨基苯磺酸钠水溶液在298.15K时的渗透系数和活度系数。由此计算了它们的超额吉布斯自由能。对活度系数随浓度的变化规律进行了讨论.

关键词: 等压法, 渗透系数, 活度系数, 超额吉布斯自由能

Abstract: The osmotic coefficients and activity coefficients of sodium benzenesulfonate, sodium beivenesulfinate, sodium p-aminobenzenesulfonate, sodium p-hydroxybenzenesulfonate and sodium m-nitrobenzenesulfonate in aqueous solution have been determined at 298.15 Kby the isopiestic method.The excess molar Gibbs free energies were calculated from the osmotic and activity coefficients.

Key words: Isopiestic method, Osmotic coefficient, Activity coefficient, Excess molar Gibbs free energy.
