Standard electrode potential (data page)
The values of standard electrode potentials are given in the table below in volts relative to the standard hydrogen electrode and are for the following conditions:
- A temperature of 298.15 K (25 °C);
- An effective concentration of 1 mol/L for each aqueous species or a species in a mercury amalgam;
- A partial pressure of 101.325 kPa (absolute) (1 atm, 1.01325 bar) for each gaseous reagent. This pressure is used because most literature data are still given for this value rather than for the current standard of 100 kPa.
- An activity of unity for each pure solid, pure liquid, or for water (solvent).
- Although many of the half cells are written for multiple electron transfers, the tabulated potentials are for a single electron transfer. All of the reactions should be divided by the stoichiometric coefficient for the electron to get the corresponding corrected reaction equation.
- Divide the potentials by 0.059 V to get pe° values, which are necessary for Nernst Equation and other thermodynamic calculations.
Legend: (s) – solid; (l) – liquid; (g) – gas; (aq) – aqueous (default for all charged species); (Hg) – amalgam.
