Webtrations, open-circuit potentials (OCP) of close to 1.23v vs. a hydrogen electrode in the same medium have been obtained in the past by special pretreat- ments (2-4). The potentials were assumed to be true reversible potentials, corresponding to a four-elec- tron reduction of oxygen to water. The potential can- Webstandards The standard hydrogen electrode (SHE) is hard to set up so it is easier to use a more convenient secondary standard which has been calibrated against the SHE. Calomel • the calomel electrode contains Hg2Cl2 • it has a standard electrode potential of +0.27V • is used as the left hand electrode to determine the potential of an unknown WebELECTROCHEMICAL SERIES Petr Vanýsek There are three tables for this electrochemical series.
