The thermodynamic properties of HCl-NiSO4-H2O system was studied by EMF measurement in the cells without liquid junction: Pt, H2(101.325 kPa)│HCl(mA), NiSO4(mB), H2O│AgCl-Ag at certain total ionic strength I =0.4、0.6、0.8、1.0、1.5、2.0 mol•kg－1 with various ionic strength fractions of NiSO4 yB=0.00、0.10、0.20、0.30、0.50、0.70 at different temperatures from 278.15～323.15 K .The activity coefficients of HCl γA in the solution have been calculated from EMF of cell (A).The results show that the activity coefficients of HCl in the solutions still obey Harned’s rule.
