Standard Electrode

Definition - What does Standard Electrode mean?

A standard electrode is an electrode used in electrochemical reactions when it is necessary to know the potential of the electrode. A standard electrode has a designated potential that is used as a reference point. This reference point is used to calculate the potential of the other electrode in the cell.

Corrosionpedia explains Standard Electrode

A standard electrode in an electrochemical reaction is the place (connector) where electrons enter or leave the cell. Electrons can enter through the standard electrode (which would make it an anode) or they can exit through the standard electrode (which would make it a cathode).

A standard electrode can be either inert or reactive. When a standard electrode is reactive, the electrode takes part in the electrolytic reaction. When a standard electrode is inert, it simply aids in the transport of electrons without being part of the reaction.
