The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at:

• Temperature ;

• Effective concentration (activity) for each aqueous or amalgamated (mercury-alloyed) species;

• Unit activity for each solvent and pure solid or liquid species; and

• Absolute partial pressure for each gaseous reagent the convention in most literature data but not the current standard state ().

Variations from these ideal conditions affect measured voltage via the Nernst equation.

Table of standard electrode potentials

Legend: (s) – solid; (l) – liquid; (g) – gas; (aq) – aqueous (default for all charged species); (Hg) – amalgam; bold – water electrolysis equations.
