| 摘 要： | 在恒定蔗糖质量分数x=0.100条件下，应用经典电动势方法测定无液体接电池的电动势：Pt,H2(1.013*10^5Pa)HCl(m),Sucrose(x),H2O(1-x)AgCl0Ag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。

| Abstract: | The Apparent thermodynamic properties of HCl-Sucrose-H2O system were studied by means of emf measurements of the cell without liquid junction. Pt,H2(1.013×105Pa)｜HCl(m),Sucrose (x),H2O(1-X)｜AgCl -Agat the mass fraction of Sucrose x=0.100 in the mixed solution, from 278.15 to 318.15K for cell. The standard electrode potential of Ag-AgCl in the mixed solution has been determined from the values of emf. The standard transfer Gibbs free energies, transfer entropy, and transfer enthalpy of HCl have been calculated. |
