Abstract
From the
emf measurements of the cell Pt, H
2 (g, 1 atm):HCl (
m),
X% tetrahydrofuran,
Y% water: AgCl, Ag the standard potentials of AgAgCl electrode have been determined in eighteen tetrahydrofuran-water mixtures at nine different temperatures in the range 15–55°C. The temperature variation of the standard
emf was utilized to calculate the standard thermodynamic functions for the cell reaction and the standard thermodynamic quantities for the transfer of one mole of HCl from water to tetrahydrofuran-water media. The primary medium effects of various solvents upon HCl were also calculated. The results have been interpreted in regard to the acid-base properties and the structure of the solvent.
