摘要
本文借助于数字式离子计,测定了在整个乙醇浓度范围内和m(HCl)分别为0.02,0.04,0.06,0.08和0.10 mol·kg^(-1)时电池:玻璃电极|HCl(m),H_2O(1-x),EtOH(x)|AgCl-Ag的电动势,并由此求得了在上述混合溶剂条件下各浓度HCl的平均活度系数γ_±和标准迁移自由能△G_t~?,其结果与现有文献值吻合较好。
By means of a numerical ionometer,this article is a EMFmeasurement for cell glass |HCl(m ),H_2O(1 - x ),EtOH(x ) | AgCl-Agin the mixtures of ethanol+water with the cocentration of HCl is 0. 02,0. 04, 0.06, 0. 08 and 0. 10 mol/kg. The evaluated mean activity coeffi-cients fot HCl and the standrd transfer free energy for it from water to themixtures have a good accordance with those from literatures.
