Electrochemical Energy Systems Quiz

Single electrode potential refers to the potential difference between an electrode and its electrolyte when no current is flowing.

The origin of single electrode potential lies in the separation of charges at the electrode-electrolyte interface. The sign conventions dictate that the potential is positive when the electrode is in contact with a solution containing its own ions at unit activity.

Standard electrode potential is the measure of the tendency of an electrode to lose or gain electrons compared to a standard hydrogen electrode. It is significant in determining the feasibility and direction of redox reactions.
