This article is very misleading. Pourbaix Diagrams show areas of ion predominance (among other things). I will pull out my old lecture notes and return to expand this when i have time.... 220.253.73.96 14:02, 29 March 2006 (UTC)
Has this ("very misleading", "needs attention from an expert") now been dealt with? - I'm no chemist, but to me the article seems sound & credible (and gives reasonable prominence to the notion of prominent ion). At the time of the Mrch_'06 comment (above) it was under 1000 bytes: within 18 months it was barely recognisable - it's nearly 10 000 bytes now, via over 100 edits. (By Mrch_'09 - "needs attention" - it was 3500 or so.) 95.149.131.76 (talk) 23:50, 8 July 2016 (UTC)
Not sure how to resolve this, the horizontal pH scale on the iron Pourbaix diagram is incorrect, counting: "0 2 4 6 8 10 11 14".
I just fixed that typo in the figure's X axis. Olawlor (talk) 06:32, 6 April 2019 (UTC)

Explanation for non-specialist readers
Can this concept be explained to readers who are not electrochemists (and therefore do not know already what it is)?
The head section could use a couple of sentences on the uses of this deiagram, ad the body of the article could include a couple of examples. --Jorge Stolfi (talk) 23:57, 29 March 2019 (UTC)
Could the vertical axis be something else?
I recall seeing on some journal paper a plot labeled "Pourbaix diagram" for copper compounds where the horizontal axis was pH, as in this article, but the vertical axis was partial pressure of CO2. The phases included malachite, azurite, copper oxide, cuprate, etc. Does that make sense? --Jorge Stolfi (talk) 00:02, 30 March 2019 (UTC)
This isn't my field, but there's a paper in Metals discussing more recent generalized Pourbaix diagrams, and they give the example of a 3D voltage-CO2-pH stability diagram.Olawlor (talk) 06:32, 6 April 2019 (UTC)
