Line 4:

I may be mistaken, but shouldn't this diagram have some kind of salt bridge in the middle to prevent spontaneous reaction of ions in solution? This would cause no current to flow into the electrodes, though would result in dissolution of the anode and depletion of the ionic species.[[User:Darkwraith|Darkwraith]] ([[User talk:Darkwraith|talk]]) 00:18, 2 August 2010 (UTC)

: Generally not that I can see. Compare with diagrams: [http://books.google.com/books?id=i-J5cFNCnZAC&pg=PA35&dq=%22three+electrode%22+potential+measurement&hl=en&ei=0TVWTP2DEIL68Aaxs4D_BA&sa=X&oi=book_result&ct=result&resnum=1&ved=0CC0Q6AEwAA#v=onepage&q=%22three%20electrode%22%20potential%20measurement&f=false this] [http://books.google.com/books?id=VXQdq0B3tnUC&pg=SA70-PA14&dq=%22three+electrode%22+potential+measurement&hl=en&ei=0TVWTP2DEIL68Aaxs4D_BA&sa=X&oi=book_result&ct=result&resnum=2&ved=0CDIQ6AEwAQ#v=onepage&q=%22three%20electrode%22%20potential%20measurement&f=false this] [http://www.google.com/imgres?imgurl=http://www.gamry.com/App_Notes/ReferenceElectrodes/RefElect_2.gif&imgrefurl=http://www.gamry.com/App_Notes/ReferenceElectrodes/ReferenceElectrodes.htm&usg=__XvbPWcDlu7OYE-nnCDAQBHOuHkY=&h=292&w=424&sz=4&hl=en&start=16&tbnid=3mtgvTXYeejz5M:&tbnh=119&tbnw=173&prev=/images%3Fq%3Dthree%2Belectrode%2Bsetup%2B%2522potential%2522%2Bdiagram%26um%3D1%26hl%3Den%26sa%3DX%26biw%3D840%26bih%3D411%26tbs%3Disch:10%2C468&um=1&itbs=1&iact=hc&vpx=391&vpy=134&dur=39&hovh=186&hovw=271&tx=166&ty=169&ei=eDRWTOfcAsH78AbX_oHCBA&page=3&ndsp=8&ved=1t:429,r:2,s:16&biw=840&bih=411 this] and many other.

== Deletion ==

Deleted this from the origin section for incoherence:

Electrode potential does not depend on the species in the reaction. Therefore the electrode potential for a half reaction of

2Cu2+(aq)+4e- -----> 2Cu(s)

has the same electrode potential as

Cu2+ (aq) +2e- -----> Cu (s)
