摘　　要：在恒定葡萄糖质量分数w=10%,应用经典电动势方法测定无液接电池的电动势:Pt,H2(101.325kPa)|HCl(m),C6H12O6(w),H2O(1-w)|AgCl-Ag根据测得该电池的电动势,确定了混合溶液中AgCl-Ag电极的标准电极电势,讨论了盐酸的迁移性质.The Apparent thermodynamic properties of HC1 - glucose - a20 system were studied by means of emf measurements of the cell without liquid junction Pt,H2（101.325kPa）｜HCl（m）,C6H12O6（W）,H2O（1-W）｜AgCl-Ag at the mass fraction of glucose w = 10% in the mixed solution, from 278.15 to 318.15 K for cell. The stand- ard electrode potential of AgCl - Ag in the mixed solution has been determined from thevalues of emf. The standard transfer Gibbs free energies, transfer entropy, and transfer enthalpy of HCI have been calculated.
