I think some of the information on this page is wrong (but I'm not an expert!). The spelling isn't great either
It seems to be in order... (BW)
Missing information: Saturated calomel electrode (SCE) is +244 mV versus the standard hydrogen electrode (SHE) at 25°C REF: D.T. Sawyer and J.L. Roberts. In: Experimental Electrochemistry for Chemists Wiley-Interscience, New York (1974), p. 42. DCAM77 (talk) 18:47, 21 August 2008 (UTC)
Pt?
editThe half-cell notation ends with Pt. What does platinum have to do with this? 207.70.169.36 (talk) 15:00, 28 May 2009 (UTC)
- It's an inert electrode[1] - it sources or sinks electrons but does not react. Also see Standard hydrogen electrode#Why platinum?. --Kkmurray (talk) 02:38, 29 May 2009 (UTC)
an electrode is half a cell
editThe "solubility product" section is just wrong. an electrode provides one end of a full galvanic cell, ie a half cell. (or part of one). using two different E_anode and E_cathode and taking their difference to get the full EMF of a full cell makes absolutely no sense in an article about an electrode (!not a full cell!) the two half reactions need to happen each in different electrodes for the cell to work. in a full cell the calomel electrode would work either as anode or cathode, but not both at the same time. What is the full cell this section refers to? i dont know, but at some point E_cell is taken to be zero "at equilibrium". that is just gibberish camouflaged as nernst equations. The following section makes sense, and the actual half cell reaction taking place in the electrode is used. i recommend keeping that section and discarding the other one 2803:9800:9504:7B33:F99C:D870:9B01:3FE3 (talk) 04:25, 21 December 2022 (UTC)
