Abstract
From the electromotive force measurements of the cell Pd | H
2
(g, 1 atm)| HBr (
m
), solvent | AgBr | Ag at nine different temperatures from 5 to 45 °C, the standard potentials of the Ag,AgBr electrode have been determined in sixteen acetone + water solvent mixtures, by an extrapolation method making use of the extended terms of the Debye-Hückel theory. The temperature variation of the standard potential has been used to calculate the standard thermodynamic functions for the cell reaction and the standard quantities for the transfer of HBr from water to the respective acetone + water media. The results have been discussed in terms of the acid-base properties and the strutural features of the solvents.
