Popis: The emfs of cells without-junction Pt, H2(g, p0)|HCl(mE)|AgCl-Ag Pt, H2(g, p0)|HCl(mE), EtOH(mN)|AgCl-Ag have been measured at 10 degree intervals from 278.15 to 318.15 K, where EtOH refers to ethanol, mE“0.005–0.1 mol.kg−1, mN“0.4–1.0 mol.kg−1. The salting constant kS of EtOH by HCl and the thermodynamic parameters of interaction, fEN (gEN. hEN, SEN, Cp,EN), of EtOH with HCl in water have been evaluated. It has been shown that kS > 0, gEN > 0, hEN > 0, SEN > 0, and CP, EN < 0. The signs of these parameters and the temperature dependence of them have been discussed on the basis of structural interaction and the group additivity models.
