2. Electrode - Wikipedia

   en.wikipedia.org/wiki/Electrode

   An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or a gas). In electrochemical cells, electrodes are essential parts that can consist of a variety of materials (chemicals) depending on the type of cell.

4. Standard electrode potential (data page) - Wikipedia

   en.wikipedia.org/wiki/Standard_electrode...

   Electrode potentials of successive elementary half-reactions cannot be directly added. However, the corresponding Gibbs free energy changes (∆G°) must satisfy ∆G° = – z FE°, where z electrons are transferred, and the Faraday constant F is the conversion factor describing Coulombs transferred per mole electrons. Those Gibbs free energy ...

5. Reference electrode - Wikipedia

   en.wikipedia.org/wiki/Reference_electrode

   A reference electrode is an electrode that has a stable and well-known electrode potential. The overall chemical reaction taking place in a cell is made up of two independent half-reactions , which describe chemical changes at the two electrodes.

6. Ion-selective electrode - Wikipedia

   en.wikipedia.org/wiki/Ion-selective_electrode

   An ion-selective electrode (ISE), also known as a specific ion electrode (SIE), is a simple membrane-based potentiometric device which measures the activity of ions in solution. [1] It is a transducer (or sensor ) that converts the change in the concentration of a specific ion dissolved in a solution into an electrical potential .
