摘要
Pt,H2(g,p0)HCl(mE)|AgCl-AgPt, 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 HCI 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.
