测定了２９３．２～３２３．２Ｋ间的７个温度下电池ＧＥ｜Ｈ２Ｏ（１－ｗ）＋Ｅｎ（ＯＨ）２（ｗ）＋ＨＣｌ（ｍ）｜ＡｇＣｌ－Ａｇ的电动势，由此求得了上述７个温度下，ｍ＝０．００２０，０．００５０，０．０１００，０．０５００，０．１０００ｍｏｌ／ｋｇ的ＨＣｌ在０～９０％乙二醇—水二元混合溶剂中的平均活度系数γ±与Ｐｉｔｚｅｒ参数；ＨＣｌ自水向各组成Ｅｎ（ＯＨ）２—Ｈ２Ｏ混合溶剂中的标准迁移自由能，标准迁移熵和标准迁移焓．最后从分子间相互作用的角度对ＨＣｌ在该混合溶剂中的热力学行为给予了理论解释．
The electromotive force of the battery GE | H2O (1-w) + En (OH) 2 (w) + HCl (m) | AgCl-Ag at 7 temperatures between 293.2 and 323.2K was measured, Temperature, m = 0.0020,0.0050,0.0100,0.0500,0.1000mol / kg HCl in 0-90% ethylene glycol - water binary mixed solvent average activity coefficient γ ± And Pitzer parameters; standard migration free energy, standard migration entropy and standard enthalpy of migration in a mixed solvent of HCl and water from each component of En (OH) 2-H2O. Finally, the thermodynamic behavior of HCl in this mixed solvent is theoretically explained from the perspective of the intermolecular interaction.
