Abstract

Thermogalvanic cells with silver chloride and quinhydrone electrodes in the HCl-H2O-1-PrOH system are studied experimentally. The results are used to determine standard entropies of thermal diffusion transport of hydrogen chloride, entropies of mobile H+ and Cl ions, and Soret coefficients of the electrolyte at 298 K. Thermal diffusion entropies and partial molar entropies of said ions in water-1-propanol solutions are calculated within the Agar model. The results are interpreted with the application of basic concepts of the De Bethune theory concerning thermal diffusion transport in electrolytes.
