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.

vad innebär det att en potential är uppmätt mot s.c.e ? 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 4 (Ans E0 = – 0.14V , therefore the reaction is non-spontaneous) 10) Calculate the e.m.f. of the following cells at 298 K. (i)Zn (s) |ZnCl 2,(0.0102m),AgCl (s) |Ag (ii) Pt , H 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 There is an example of adding a Luggin Capillary to reference electrode. Se hela listan på de.wikipedia.org Onderstaande waarden zijn standaardelektrodepotentialen van waterige oplossingen bij 25 °C. De tabel is vergelijkbaar met tabel 48 uit "BINAS".Voor een uitgebreidere versie, zie: "Handbook of Chemistry and Physics", index entry: electrochemical series.

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. Silverkloriden är ju svårlöslig så halten av silverjoner är mycket låg. Reduction Half-Reaction Reduction Potential - E0 in Volts Ag+-+ e → Ag 0.7996 Ag2+ ++ e-→ Ag 1.980 Ag3+-+ e → Ag2+ 1.8 AgBr + e-→ Ag + Br 0.0713 AgCl + e-→ Ag + Cl 0.2223 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 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.

氯化银电极的电极电位可以从银电极的电极电位得出银电极：Ag+ + e ----> Ag E0(Ag+/Ag)能斯特方程：E=E0(Ag+/Ag) + 0.05916log[Ag+]在银电极反应方程两边加上Cl-,有：Cl- + Ag+ + e ----> Ag + Cl- E0(AgCl/Ag)即,Ag 2011-12-31 · AG+ + Cl- -----> AgCl or Ag+ + 2Cl- -----> AgCl2 As doesn't ag have two elelctrons in its outter shell. And so two chlroines are needed to form a ionic bond.
