are measured in an electrochemical system.
Electrochemical System
The reference electrode typically has a stable and well-known thermodynamic potential. The high stability of the reference electrode is usually achieved by employing a redox
Redox
system with constant (buffered or saturated) concentrations of the ions or molecules involved in the redox half-reaction. When used as part of a three-electrode system,
