Abstract
Electromotive force measurements were carried out on the HCl−ZnCl2−H2O system at constant total ionic strengths of 0.1, 0.2, 0.5, 1.0 and 2.0 mol-kg−1 at 25 and 35°C using a cell consisting of Pt, H2(g, 1 atm)|HCl(mA), ZnCl2(mB)|AgCl/Ag. The data were interpreted by the mixed electrolyte equations of Pitzer and Kim in order to evaluate mixing ion-interaction parameters. The activity coefficients of ZnCl2 and the Gibbs excess free energies of mixing are calculated and presented at I=2.0 mol-kg−1 and compared with similar systems containing transition metal chlorides.
