摘要： 测量电池Pt,H2(g,1atm)|HCl(IA),CoCl2(IB)|AgCl-Ag的电动势,确定了HCl(A)+CoCl2(B)+H2O体系中HCl在总离子强度I=0.5到5.0molekg-1和温度5—45℃下的活度系数γA,其中IA和IB分别是HCl和CoCl2的离子强度。

Abstract: Electromotive force of cell Pt,H2(g, latm)|HCl(IA),CoCl2(IB)| AgCl-Ag has been measured and the activity coefficients determined in the system with the total ionic strength I between 0.5 and 5.0 mole· kg-1 over the temperature range 5-45℃ obey the Harned's Rule. Under the condition of constant components of mixtures the logarithm of HCl activity coefficients is a linear function for temperatures, Ig γA = a + bT, whereγAis the activity coefficient of HCl, a and b are constants related to the component and total ionic strength in mixed solutions.
