Une électrode au chlorure d'argent est une électrode de référence, couramment utilisée en électrochimie.Elle est par exemple souvent utilisée comme électrode de référence interne dans les électrodes de verre pour la mesure du pH.

By looking at a table of standard reduction potentials!. One of the half-reactions must be reversed to yield an oxidation.Reverse the half-reaction that will yield the highest (positive) net emf for the cell. Remember that when one reverses a reaction, the sign of Eº (+ or –) for that reaction is also reversed.

dry NASICON-based surface electrodes and pregelled Ag−AgCl electrodes is Gondran, C., Siebert, E., Yacoub, S., andNovakov, E. (1995b): 'Dry electrode 

The electrode is a silver wire that is coated with a thin layer of silver chloride, either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid or electrochemically by oxidising the silver in a chloride solution. Ag/AgCl reference electrode is a kind of commonly used reference electrodes. AgCl + e = Ag + Cl- E0 = 0.199V vs. NHE 25 C D.J.Ives and G.J.Janz, "Reference Electrodes," Academic Press, New York, 1961 The electrode is composed of Ag/AgCl/Saturated KCl solution. Dip your made Ag/AgCl reference electrode in a beaker with 1 M HCl solution and take a Pt foil in to the beaker, pursue with H 2 gas (thus the E0 of the hydrogen electrode will not be 0 *) Pluspolens e0 (för Ag/AgCl) är ca 0.20 V medan Ag+/Ag har e0 som är ca 0.80 V . Försöker man beräkna emk för den här cellen kan man inte använda e0 för Ag+/Ag eftersom aktiviteten (ungefär koncentrationen) för Ag+ är mycket långt från 1.
