N2 - The e.m.f. of the cell Pt, H2 (g, 1 atm) |HCl(m), propan-2-ol| AgCl, Ag at 5°C intervals from 5 to 45°C for hydrochloric acid solutions in the range 0.005 to 0.1 mol kg-1 has been used to calculate (a) the standard e.m.f. of the cell at each temperature, (b) the mean molal activity coefficients of HCl at 25°C, (c) the primary medium effect, and (d) the thermodynamic transfer quantities, ΔGto, ΔHto, ΔSto, and ΔCpto for the transfer of HCl from water to propan-2-ol. The significance of the evaluated thermodynamic functions for the transfer process has been discussed in relation to the acid-base strength, as well as the structural features of the solvents (water and propan-2-ol).
