Thermodynamics of transfer of hydrochloric acid from water to aqueous glucose at 25°C

Abstract

Enthalpies of transfer of HCl from water to aqueous glucose were determined calorimetrically at 25°C at several mixed solvent compositions ranging up to glucose mole fraction X3=0.0624 (40 wt. %). These were combined with free energies of transfer calculated from emf measurements to yield entropies of transfer, and all properties are compared with those observed for HCl and NaCl transfer to other aqueous nonelectrolyte mixed solvents.
