N2 - Standard potentials of the Ag−AgCl electrode in glycerol have been determined by a polynomial curve-fitting program from e.m.f. measurements of cells of the type Pt; H2 (g, 1 atm) |HCl (m), glycerol| AgCl, Ag, at nine different temperatures in the range 5 to 45°C. The primary medium effect of the solvent upon HCl was also calculated. The temperature variation of the difference in standard e.m.f. in two solvents (water and pure glycerol) was utilized to calculate the thermodynamic quantities (ΔGo, ΔHo, ΔSo, and ΔCpo) for the transfer of one mole of HCl from water to glycerol. The results have been interpreted in regard to the acid-base properties and the structure of the solvent.
