Talk:Iron(III) chloride

message: The article is about the 3 chloride, but one of the production methods listed is;
"Solutions of iron(III) chloride are produced industrially both from iron and from ore, in a closed-loop process.
   1. Dissolving pure iron in a solution of iron(III) chloride
          Fe(s) + 2 FeCl3(aq) → 3 FeCl2(aq)"
Reducing the 3 chloride to the 2.  —Preceding unsigned comment added by 109.152.25.154 (talk) 12:49, 4 January 2011 (UTC)

Hi Wim- does this template go on the talk page, or the article page?  Does it apply if we use any of the templates, or just certain ones? Thanks, Walkerma 21:25, 9 Apr 2005 (UTC)
replies: text: Thanks, I wrote a lot of this.  Yes, I know they are very different beasts, just like with SnCl4 and AlCl3.  You're doing a nice job on rewriting the page, keep it up!  I think it would be hard justifying separate pages for the anhydrous and the hydrate, we need to find a format that works well without conflating.  What you see is my attempt, in effect a first attempt, I started from a blank page.  Whatever you can come up with to improve on that may be worth discussing, perhaps we can apply an ideas you have to the many other halides that have similar issues.  One minor thing, Greenwood & Earnshaw say anhydrous FeCl3 is brown-black; where are you getting the green-black color from?  Thanks for your excellent work, Walkerma 19:41, 12 April 2006 (UTC)

message: Members of the Wikipedia:WikiProject Good articles are in the process of doing a re-review of current Good Article listings to ensure compliance with the standards of the Good Article Criteria. (Discussion of the changes and re-review can be found here). A significant change to the GA criteria is the mandatory use of some sort of in-line citation (In accordance to WP:CITE) to be used in order for an article to pass the verification and reference criteria. Currently this article does not include in-line citations. It is recommended that the article's editors take a look at the inclusion of in-line citations as well as how the article stacks up against the rest of the Good Article criteria. GA reviewers will give you at least a week's time from the date of this notice to work on the in-line citations before doing a full re-review and deciding if the article still merits being considered a Good Article or would need to be de-listed. If you have any questions, please don't hesitate to contact us on the Good Article project talk page or you may contact me personally. On behalf of the Good Articles Project, I want to thank you for all the time and effort that you have put into working on this article and improving the overall quality of the Wikipedia project.

thread_title:  GA Re-Review and In-line citations 

message: Just a note for anyone to edit, as I don't know which is right, is the formula for Iron(III) Chloride FeCl3 or Cl3Fe. I'm asking because in the first paragraph it says FeCl3 but in the infobox on the side it says Cl3Fe. Can someone fix this error to which ever one is correct as I do not know the correct formula. ☺EfansayT/C☺ 04:33, 2 July 2007 (UTC)
replies: text: Either one is right, depending on which convention you are following.  The usual convention for binary compounds like this is to put the metal first, but the table uses the Hill formula system which goes C then H then others alphabetically. Walkerma 14:45, 2 July 2007 (UTC)
thread_title:  The formula for Iron (III) Chloride 

message: Conducting another GA sweeps review to re-review all Good Articles to verify that they continue to meet the Good Article criteria. This article meets all criteria except the inline citation criteria, as there are significant sections of the article that are not cited. I don't believe this is a major issue, as it looks like this can be solved by converted the 'further reading' items over to inline citations. If someone familiar with these sources could do this, the article can remain listed at WP:GA. I'll put this on hold at GA sweeps until this is done. Cheers! Dr. Cash 19:53, 25 October 2007 (UTC)
replies: text: Ok, the article looks acceptable now, although there is still information under 'Other uses' that should be sourced. That particular section is also looking rather "listy", and could be written a little better. Other than that, it looks ok. Dr. Cash (talk) 17:00, 10 December 2007 (UTC)

message: Sulfur dioxide, according to the Standard electrode potential (data page), is not strong enough to oxidize iron II to iron III. The reduction potential for sulfur dioxide to sulfur is only +0.50. The potential for oxidation of iron II to iron III is +0.77. (The potential sign is reversed for oxidation, as the table is for standard reduction potentials. The reduction potential has to be higher than the oxidation potential for the reaction to occur spontaneously (e.g., without any electric current or extreme heat). --Cheminterest (talk) 21:52, 24 March 2010 (UTC)

message: Just as Copper Sulphate appears white when anhydrous AND blue when hydrated, so I would guess that Iron (III) Chloride has different colours in its different hydrated forms.  WHY DOES THE PICTURE SHOW IRON (III) CHLORIDE HEXAHYDRATE *AND NOT* THE ANHYDROUS FORM (assuming that these are the only forms of Iron (III) Chloride - something I cannot be certain of myself).  I have a picture of what I believe to be ANHYDROUS Iron (III) Chloride, it is dark green to the point of being black (as stated in the text).  So clearly, the text reinforces the fact that Anhydrous Iron (III) Chloride is NOT Yellow (as confusingly shown in the picture) BUT that it is Dark-Green/Almost Black.  
WHAT FOLLOWS MAY NOT BE ABSOLUTELY TRUE, BUT LIKELY IS and is based on past sample notes: 
I also believe that Anhydrous Iron (III) Chloride can APPEAR to melt at 37 degrees C (according to the Wikipedia page ONLY the Hexahydrate melts at this temperature).  This leads me to conclude that THE WIKIPEDIA PAGE *has a Devil in the detail* IN RELATION TO THE MELTING POINTS OF ANHYDROUS Iron (III) Chloride **AS** there is a tendency for Anhydrous Iron (III) Chloride to become hydrated in air and THEN melt due to its Deliquescence.  Thus, naive attempts to measure the melting point of Anhydrous (III) Chloride in Air ought to take into account that energy will be directed towards evaporating absorbed moisture from the atmosphere AND the Water of Crystallisation (ie: the water that makes hexahydrate hydrated). 
 
According to the information in the article, what happens is that the HEXAHYDRATE melts when heated, then at 100 degrees C, the water evaporates, at which point the sample becomes SOLID Anhydrous Iron (III) Chloride AND THEN, at 306 degrees C, the sample MELTS AGAIN (TWICE!).  This is notable.
