Primary Reference Electrode Diagram. Maharashtra state board hsc science general 12th board exam. Reference electrodes used are preferably reversible type electrodes.
A platinum leads b silver wire coated with silver chloride c copper wire d platinum reference electrode. The electrode whose potential is arbitrarily fixed or is exactly known at a given constant temperature is known as a reference electrode. 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.
Question bank solutions 11020.
Identify the unmarked component. Why is standard hydrogen electrode called as the primary reference electrode. A reference electrode is also needed with these ise so that the varying potential of these ise can be compared with the steady potential produced by reference electrode. Using reference electrodes unknown potential of any other single electrode can be found out e g.
