This is a reference electrode to which all electrodes are calculated in terms of electrode potential. The reference electrodes can be classified in to two types i primary reference electrodes ex. The potential of the resulting galvanic cell is determined experimentally.
The potential of the resulting galvanic cell is determined experimentally.
The standard reference point for electrochemical potentials is the hydrogen electrode h h2. E it is used as a primary reference electrode for determining the standard electrode potential of an unknown electrode. Standard hydrogen electrode is used as a primary reference electrode to know the standard electrode potentials relative of elements and other electrodes. A reference electrode is an electrode which has a stable and well known electrode potential the high stability of the electrode potential is usually reached by employing a redox system with constant buffered or saturated concentrations of each participant of the redox reaction.
