Abstract

The standard potentials of the silver/silver-chloride electrode in 95 wt-% 1-propanol have been determined by means of a theoretically justified polynomial curve-fitting programme. The emf measurements of cells of the type Pt; H2(g, 1 atm) HCl (m) in 95 wt-% 1-propanol, AgCl/Ag at nine temperatures from 5-45°C have been used to evaluate (a) the mean molal activity coefficient, (b) the primary medium effect, (c) the relative partial molal enthalpy and heat capacity of HCl, and (d) the thermodynamic constants for the process of transfer of HCl from water to 95 wt-% 1-propanol. The significance of the data with respect to the solvent structure and acid-base properties is discussed.
