electrode potential
Noun
Meaning
electrode potential (plural electrode potentials)
(chemistry, physics) the potential difference of a half-reaction which occurs across a reversible cell made up of any electrode and a standard hydrogen electrode
Examples
Conversely, if the measured potential is negative, the electrode is more oxidizing than the SHE (such as Zn in ZnSO 4 where the standard electrode potential is −0.76 V).
In a cell, there will be an electrode potential for the cathode, and an electrode potential for the anode.
In principle the voltage required to electrolyze a salt solution can be derived from the standard electrode potential for the reactions at the anode and cathode.
It follows that electrode potential is proportional to pH when pH is defined in terms of activity.
Measurement Three-electrode setup for measurement of electrode potential.
Standard electrode potential main To allow prediction of the cell potential, tabulations of standard electrode potential are available.
