Abstract
Standard potentials of the Ag, AgBr electrode in eighteen propan-2-ol + water mixtures have been determined from e.m.f. measurements on the cell Pt|H

(g, 1 atm)|HBr (
m
), solvent|AgBr|Ag at nine temperatures from 15 to 55°C at 5°C intervals. These values were used to evaluate the standard thermodynamic functions for the cell reaction, the primary medium effects of various solvents upon HBr and the standard thermodynamic quantities for the transfer of one mole of HBr from water to propan-2-ol + water solvents. The results have been discussed in the light of ion-solvent interactions as well as the structural changes of these solvents.
