From the emf measurements of the cell Na- or K-glass electrode|2-butoxyethanol, H2O, NaCl or KCl|Cl ion-selective electrode, the standard potentials were determined at 298 K for five different compositions of the solvent. From the emf data the mean activity coefficients of NaCl and KCl were calculated and fitted to an empirical equation. The standard Gibbs free energies of transfer of NaCl and KCl from water to mixtures of water and 2-butoxyethanol were calculated from the cell potential.
