Accurate Potentials of Hg/HgO Electrodes: Practical Parameters for Reporting Alkaline Water Electrolysis Overpotentials

“…Hence, in eq , the OH – activity mainly contributes to the deviation from the standard potential of the Hg/HgO electrode. Additionally, as the activities of pure substances in condensed phases (i.e., solids or liquids) at 1 atm are one by definition, the activities of Hg and HgO become one. All things considered, the potential of the Hg/HgO electrode (1 M NaOH/KOH) should not become equal to E Hg/HgO ° .…”

“…29 Hence, in eq 3, the OH − activity mainly contributes to the deviation from the standard potential of the Hg/HgO electrode. Additionally, as the activities of pure substances in condensed phases (i.e., solids or liquids) at 1 atm are one by definition, 30 the activities of Hg and HgO become one. All things considered, the potential of the Hg/HgO electrode ( There are several works that have experimentally and theoretically obtained the potentials of Hg/HgO electrodes with NaOH, KOH, Ca(OH) 2 , and Ba(OH) 2 used as internal aqueous solutions at different concentrations.…”
