The standard electrode potential for the Fl 2 + / Fl couple is predicted to be " 0.9 V.
32.
Other example are many redox indicators, which undergo reversible color change between colored and colorless form at a specific electrode potential.
33.
Modern industrial scale production involves the electrochemical oxidation of iodates, on a PbO 2 anode, with the following standard electrode potential:
34.
If the second electrode is also at standard conditions, then the measured cell potential is called the standard electrode potential for the electrode.
35.
A standard cell potential can be determined by looking up the standard electrode potentials for both electrodes ( sometimes called half cell potentials ).
36.
An accurate and practical method to measure an electrode's potential in isolation ( absolute electrode potential ) has yet to be developed.
37.
Using standard electrode potentials in this way must be done with caution as factors such as complex formation and solvation may affect the reaction.
38.
Changes in the stoichiometric coefficients of a balanced cell equation will not change E?red value because the standard electrode potential is an intensive property.
39.
Ideally, electrode potential, " E ", follows the Nernst equation, which, for the hydrogen ion can be written as
40.
To avoid possible ambiguities, the electrode potential thus defined can also be referred to as " Gibbs-Stockholm electrode potential ".
