摘要: 本文用EMF法测定了25.00±0.02℃时,总离子强度由0.1到5.0molkg-1的HO1-NiCl2-H2O体系中盐酸的活度系数,列入表1。

Abstract: Activity coefficient for HCl in the system HCl+ NiCl2 + H2Owith constant total ionic strengths have been measured at 298.15Kby the EMFmethod. Treated by using Har-ned's and Pitzer's equations for the mixed electrolyte solutions the results showed that the coefficient obeys Harned's Rule in the mentioned condition above. The mixing parameters 0 and ψ in Pitzer's equation have been obtained by using three methods and the activity coeffcients for the salt NiCl2 derived from them are in agreement with each other within expcrement error.
