| 摘 要： | 本文采用电动势法测定了无液体接界电池Pt,H_2(101.3KPa)|HCl(m),DMSO(x),EtOH(y),H_2O|AgCl-Ag的电动势。其中当DMSO的含量分别恒定在x=10.20%(wt)时,EtOH的含量分别取y=10、20、30%(wt),温度区间为298.15～318.15k;温度间隔为5K.根据实验测得的电动势,计算了迁移热力学函;发现当DMSO%(wt)恒定时,ΔG_t~0与EtOH%(wt)有线性关系,而ΔH_t~0和TAS_t~0随EtOH%(wt)的改变,都有最高点出现。并据此讨论了溶液的微观结构。

| Abstract: | In this paper,Emf's of the cell(A):pt,H_2(101.3KPa)|HCl(m),DMSO(x),EtOH(y),H_2O|Δgcl-Ag,were measured at ethanol 10,20,30%(wt)when concentrations of DMSO were fixed respectivelyin 10 and 20(wt)% from 298.15 to 318.15K.By using least square regression method the standardelectromotive forces were calculated.Futhermore,the transfer Gibbs free energe,enthalpy and entropywere calculated.In terms of the exprimental data of the transfer thermodynamic functions,themicro-structure of the electrolyte solution was also discussed. |
