Solution for Calculate the electrode potential of a silver electrode immersed in a 0.2500M solution of KCl using (i) E0 Ag+/Ag=0.799v (b) E0 AgCl/Ag=0.222v

Applications. Commercial reference electrodes consist of a plastic tube electrode body. 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 (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. This table is an alphabetical listing of common reduction half-reactions and their standard reduction potential, E 0, at 25 C, and 1 atmosphere of pressure. The standard reduction potentials are all based on the standard hydrogen electrode. 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.

How do we know which metal will become oxidized and which metal ion reduced?. 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.

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 0.00V Solution for Calculate the electrode potential of a silver electrode immersed in a 0.2500M solution of KCl using (i) E0 Ag+/Ag=0.799v (b) E0 AgCl/Ag=0.222v To summarize, the potential of the Ag/AgCl electrode depends on the concentration of the solution used in the electrode itself. If you have a sat. solution then the potential is +0.197V. To convert 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] –. The data values of standard electrode potentials (E°) are given in the table below, in volts relative to the standard hydrogen electrode, and are for the following conditions: Standard Electrode Potentials in Aqueous Solution at 25°C Cathode (Reduction) Half-Reaction: Standard Potential E ° (volts): Li + (aq) + e--> Li(s)-3.04: K + (aq 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.

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. Silverkloriden är ju svårlöslig så halten av silverjoner är mycket låg.
