Saturated calomel electrode standard reduction potential value

Lipoi( acid is rediunblo at the dropping mercury electrode (Reed et al., 1953a Ke, 1957). The half-wave potential at pH 7.0 is —0.567 volt versus the saturated calomel electrode (Ke, 1957). This value corresponds to a reduction potential of —0.325 volt with respect to the standard hydrogen electrode. The reduction potential of the dihydrolipoic acid-lipoic acid system has been calculated from the equilibrium constant of the dihydro-... 

Electrochemical measurements were performed as previously described . The working electrode was either a platinum flag (Sargent) (oxidation) or hanging mercury drop (HMDE) (reduction). The reference was a saturated calomel electrode (SCEK All potentials are reported vs. NHE by addition of 0.24 V to the SCE reduction values, while the internal ferrocene/ferrocenium couple (E = 0.40 7) was used as the standard in oxidations. 

V. 19-8. In a calomel electrode, reduction potential depends on the chloride potential. Therefore, the standard reduction potential for a calomel electrode has a different chloride concentration from the saturated calomel electrode. 19-9. Dry cells and lead-acid cells "run down" as the concentrations of reactants and products eventually reach their equilibrium values, where A,G and Eceii both become 0. This does not happen in a fuel cell because fuel is continuously added. 19-10. Both AI and Zn can be used because they are more active than Fe ...
