Abstract

Emf measurements of cells of the type Pt, H₂ (g, 1 atm) |HCl (m), 1-PrOH (X), H₂O (Y)| AgCl/Ag at 5-45°C and m 0·005-0·15 mol/kg have been used to derive the standard potentials of the cells by a theoretically justified polynomial curve-fitting technique, the mean activity coefficient of HCl (molal scale), the medium effect, the relative partial molal heat content and the thermodynamic function (mol-fraction scale) for the transfer of HCl from water to the respective 1-PrOH-H₂O media. E_m° is expressed as a function of temperature. The electrostatic part of the thermodynamic functions was computed according to Born's model and hence the chemical effect of the solvents on the transfer process has been evaluated. The significance of the results discussed with regard to the acid-base properties and the structural effects of the solvents with further additions of 1-PrOH.
