In electrochemistry, electrode potential is the voltage of a galvanic cell built from a standard reference electrode and another electrode to be characterized. By convention, the reference electrode is the standard hydrogen electrode (SHE).
A potential difference developing between the electrode and the electrolyte is known as electrode potential.

Oct 25, 2022 · The standard electrode potential, \(E^{\circ}\), for a half-reaction is the potential when all species are present at unit activity or, for gases, unit fugacity.
When using a galvanic cell to measure the concentration of a substance, we are generally interested in the potential of only one of the electrodes of the cell, the so-called indicator electrode, whose potential is related to the concentration of the substance being measured.
The tendency of an electrode to lose or gain electrons i.e undergo oxidation or reduction when it is dipped in the solution containing its own ions is termed electrode potential or single electrode potential.
Jul 12, 2023 · The potential (E cell) of the cell, measured in volts, is the difference in electrical potential between the two half-reactions and is related to the energy needed to move a charged particle in an electric field. In the cell we have described, the voltmeter indicates a potential of 1.10 V (part (a) in Figure \(\PageIndex{3}\)).
