✦ Synopsis

Values of the e.m.f. for the cell without liquid junction: Pt|H 2 (p = 101.325 kPa)|HCl(m A ), GaCl 3 (m B ), H 2 O|AgCl|Ag, are reported at five different temperatures from 278.15 K to 318.15 K. The standard association constants K of the ion pair [GaCl] 2+ were determined by a linear extrapolation on the basis of the extended Debye-HΓΌckel equation. The thermodynamic quantities for the ion association process were calculated, and the association entropy was found to be the main driving force in the process.
