Abstract: The thermodynamic properties of the system HCl-In2(SO4)3-H2O were studied by EMF measurement in cells without liquid junction: Pt, H2(101.325 kPa )│HCl(mA), In2(SO4)3(mB),H2O│AgCl-Ag (A) at constant total ionic strength I = 0.2、0.4、0.6、0.8、1.0、1.5 mol•kg-1 and yB=0、0.10、0.20、0.30、0.50、0.70 at different temperatures ranging from 278.15~318.15 K. The activity coefficients of HCl γA in the solution have been determined from cell (A).

Key words: Activity coefficients, EMF, Ionic strength, Indium Sulfate
