摘要： 我们测定了总离子强度Ⅰ恒定1.0molkg-1,5-45℃时无液接电池Pt,H2(1atm)|HCl(mA),KCI(mB),PrOH(x),H2O(1-x)|AgCl-Ag(A)的电动势,其中mA和mB分别为HCl和NiCl2的质量摩尔浓度,x为正丙醇PrOH在混合溶剂中的摩尔分数,x=0.02,0.05,0.08和0.12。

Abstract: This paper reports that emf of cellPt,H2(latm) |HCl(mA),KCl(mB),RrOH(x),H2O(1-x) | AgCl-Ag(A) have been made at 5-45℃ regions and x= 0.02,0.05,0.08 and 0.12, where x is molar fraction of PrOH in mixed solvents.The results show that HCl also obeys Harned' s Rule and logarithms of activity coefficients of HCl are a linear function for temperature.Relative patial molar enthalpy of HCl have been discussed.
