51Palladium-hydrogen electrode — The Palladium Hydrogen electrode (Abbreviation: Pd/H2) is one of the common reference electrodes used in electrochemical study. Most of its characteristics are similar to the standard hydrogen electrode (with platinum). But palladium has one… …
52Quinhydrone electrode — is one of several oxidation reduction electrode s used for measuring hydrogen ion concentration or pH. It consists of an inert metal wire (usually platinum) in contact with quinhydrone crystals and a water based solution. Quinhydrone is slightly… …
53Working electrode — The working electrode, is the electrode in an electrochemical system on which the reaction of interest is occurring. The working electrode is often used in conjunction with an auxiliary electrode, and a reference electrode in a three electrode… …
54Standard electrode potential (data page) — The standard electrode potentials are electrode potentials of half cells at equilibrium. They can be used to determine the potential of an electrochemical cell or galvanic cell, or a position of equilibrium for an electrochemical (redox) reaction …
55Redox electrode — A redox electrode is an electrode made from electron conductive material and characterized by high chemical stability in the solution under test. It is used for measuring the redox potential of a specific redox system in solution, and for… …
56calomel electrode — noun : a reference electrode consisting of mercury, calomel, and potassium chloride solution * * * Physical Chem. a reference electrode consisting of calomel, mercury, and a solution of potassium chloride …
57ion-selective electrode — An electrode half cell, with a semi permeable membrane that is permeable only to a single ion. The electrical potential measured between this and a reference half cell (eg. a calomel electrode) is thus the Nernst potential for the ion. Given that …
58hydrogen electrode — noun : an electrode composed typically of platinum black on platinum over which a stream of hydrogen is bubbled and that under specified conditions serves as the standard electrode with an assigned potential of zero to which all other electrode… …
59glass electrode — noun : an electrode that consists typically of a glass tube sealed at the bottom with a thin walled glass bulb containing a solution of constant pH (as a chloride buffer) and a silver silver chloride reference electrode and that is immersed in an …
60Mixed metal oxide electrode — Mixed metal oxide (MMO) electrodes are devices with useful properties for chemical electrolysis. The term refers to electrodes in which the surface contains two kinds of metal oxides. One kind, usually RuO2, IrO2, or PtO0.12, conducts electricity …
