  2. Standard electrode potential - Wikipedia

    en.wikipedia.org/wiki/Standard_electrode_potential

    The electric potential also varies with temperature, concentration and pressure. Since the oxidation potential of a half-reaction is the negative of the reduction potential in a redox reaction, it is sufficient to calculate either one of the potentials. Therefore, standard electrode potential is commonly written as standard reduction potential.

  3. Standard electrode potential (data page) - Wikipedia

    en.wikipedia.org/wiki/Standard_electrode...

    The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at: Temperature 298.15 K (25.00 °C; 77.00 °F); Effective concentration (activity) 1 mol/L for each aqueous or amalgamated (mercury-alloyed) species;

  4. Electrode potential - Wikipedia

    en.wikipedia.org/wiki/Electrode_potential

    In electrochemistry, electrode potential is the voltage of a galvanic cell built from a standard reference electrode and another electrode to be characterized. [1] By convention, the reference electrode is the standard hydrogen electrode (SHE). It is defined to have a potential of zero volts. It may also be defined as the potential difference ...

  5. Absolute electrode potential - Wikipedia

    en.wikipedia.org/wiki/Absolute_electrode_potential

    Absolute electrode potential, in electrochemistry, according to an IUPAC definition, [1] is the electrode potential of a metal measured with respect to a universal reference system (without any additional metal–solution interface).

  6. Standard hydrogen electrode - Wikipedia

    en.wikipedia.org/wiki/Standard_hydrogen_electrode

    Its absolute electrode potential is estimated to be 4.44 ± 0.02 V [1] at 25 °C, but to form a basis for comparison with all other electrochemical reactions, hydrogen's standard electrode potential (E°) is declared to be zero volts at any temperature. [2]

    The formal potential is thus the reversible potential of an electrode at equilibrium immersed in a solution where reactants and products are at unit concentration. [4] If any small incremental change of potential causes a change in the direction of the reaction, i.e. from reduction to oxidation or vice versa , the system is close to equilibrium ...

  8. Silver chloride electrode - Wikipedia

    en.wikipedia.org/wiki/Silver_chloride_electrode

    The standard electrode potential E 0 against standard hydrogen electrode (SHE) is 0.230 V ± 10 mV. [citation needed] The potential is however very sensitive to traces of bromide ions which make it more negative. The more exact standard potential given by an IUPAC review paper is +0.22249 V, with a standard deviation of 0.13 mV at 25 °C. [2]

    For example, for oxygen, the species would be in the order O 2 (0), H 2 O 2 (–1), H 2 O (-2): The arrow between O 2 and H 2 O 2 has a value +0.68 V over it, it indicates that the standard electrode potential for the reaction: O 2 (g) + 2 H + + 2 e − ⇄ H 2 O 2 (aq) is 0.68 volts.
