摘要：

Standard potentials of the silver-silver chloride electrode in eighteen glycerol-water mixtures containing up to 90% by weight glycerol, have been determined from e.m.f. measurements of cells of the type Pt, H2 (gas, 1 atm); HCl (m), X% glycerol, Y% water; AgCl, Ag, at nine different temperatures in the range 15 to 55°C. The standard molal potential in the various solvent mixtures has been expressed as a function of temperature. Standard thermodynamic quantities for cell reaction and the primary medium effects of various solvents upon HCl were also calculated. The temperature variation of the standard potential was utilized to calculate the thermodynamic quantities for the transfer of one mole of HCl from water to glycerol-water media. The results have been interpreted in regard to the acid-base properties and the structure of the solvent. © 1978 Elsevier Sequoia S.A.
