The relevant half cell equation is: AgCl (s) + e – Ag (s) + Cl – Silver chloride is quite insoluble in water (~0.2 mg/100 mL), but is slightly more soluble in concentrated chloride solutions owing to the formation of the complex ion [AgCl 2] –.

*) 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. Silverkloriden är ju svårlöslig så halten av silverjoner är mycket låg.
A glass electrode is generally used for this purpose, in which an internal Ag/AgCl electrode is immersed in a 0.10 M HCl solution that is separated from the solution by a very thin glass membrane (part (b) in Figure \(\PageIndex{5}\)). The glass membrane absorbs protons, which affects the measured potential. AgCl(s) + e-===> Ag(s) + Cl-(aq) is E0(AgCl/Ag) = 0.22 V. What is the anode/cathode ratio of the activities of the Cl-(aq) ion. a(Cl-) A / a(Cl-) C. if the Ag (s) + Cl – (s) → AgCl (s) + e – This electrode usually takes the form of a piece of silver wire coated with AgCl.
Ag solid = AgCl solid = Cl solution The potential of the electrode is dependent on the concentration of the chloride ions in solution and temperature as governed by the Nernst equation. ET = E0 - RT/nF ln Cl- (in moles/litre) ET = Electrode Potential measured in Volts between a metal electrode (steel structure) and a reference electrode
The following tables give the potentials of several commonly used reference electrodes. Various filling solutions are listed where data was available. Note that the nature and concentration of the filling solution can dramatically change the potential!

Ag (s) + Cl – (s) → AgCl (s) + e – This electrode usually takes the form of a piece of silver wire coated with AgCl. The coating is done by making the silver the anode in an electrolytic cell containing HCl; the Ag + ions combine with Cl – ions as fast as they are formed at the silver surface.
