The graphite-sulfate lamellar compounds—I: Thermodynamic properties, new data

The fractional and total thermodynamic values ΔG°, ΔH° and ΔS° are calculated for the electrochemical formation of various stage graphite hydrogenosulfates (GHS) from pyrographite and 18 MH 2SO 4, based on emf measurements of the GHS/18MH 2SO 4/Hg 2SO 4/Hg cell. The disagreement between our results...

Description
Summary:The fractional and total thermodynamic values ΔG°, ΔH° and ΔS° are calculated for the electrochemical formation of various stage graphite hydrogenosulfates (GHS) from pyrographite and 18 MH 2SO 4, based on emf measurements of the GHS/18MH 2SO 4/Hg 2SO 4/Hg cell. The disagreement between our results and the previous work of Aronson et al. is explained.
