Your edits to Sulfur trioxideHi! I saw your additions to sulfur trioxide. Good work. A nice addition, and nice info. Indeed, needs some references. About that, you name some references in one of your edit-summaries. To insert references, one of the methods is to use the <ref>whatever</ref>-method. If the article also has a references section with the <references/> tag in it, referencing will be automatically done. If you use the same reference again, the first one should get a <ref name=whatever>whatever</ref>, the second one can than just be written down as <ref name=whatever/> (not the / at the end of the ref). Works quite easy. Hope to see you around. We need some people adding info to chemical pages. Many are just stubs. So, keep up the good work! --Dirk Beetstra T C 19:00, 13 August 2006 (UTC) Hey Karlhahn. Feel free to continue to work on SO3. Your work was great. I am still tweaking this thing. I just did not want readers to confuse molecular structure and crystal structure (deals with packing, although chemists use the term loosely). Also the implied thermodynamics were weird, until one understands that the "stable" forms are not SO3 but a partial hydrate. I have been reading on the same topic. Keep up the good work, we need people who know chemistry.--Smokefoot 22:25, 21 August 2006 (UTC) IodineWhat I asserted was that it could not exist as a liquid at standard conditions ( 1 bar absolute and 0 C), though I could have said room temperture. The melting point is quite a bit higher. Badocter 20:39, 20 September 2006 (UTC) SandboxHi there. I've moved the article you created KarlsSandbox to a user subpage for you because personal sandboxes shouldn't be created in the main article space. Your sandbox is now located at User:Karlhahn/KarlsSandbox. --Casper2k3 12:38, 3 October 2006 (UTC)
Calcium carbonateNice work on clarifying the solubility stuff, thanks for that. I hope to do a major article expansion/rewrite on calcium carbonate early next year (I did some of these in summer 2005 on sodium sulfate, hydrogen peroxide, sulfuric acid and sodium hydroxide). Would you collaborate with me on that work? Thanks again, Walkerma 04:18, 11 October 2006 (UTC)
Regarding the geological test, I may check with our geology department to see what they say about analysis. For a chemist, fizzing with HCl is not a valid test, but it may be appropriate in geology. Unless there are specific chemical tests for identifying CaCO3, I don't think we try to cover that aspect - unless you think otherwise. And please add to the list! BTW, I think I saw a list of the top 1000 or 2000 articles in Wikipedia (in 2004) in terms of Google traffic, and I seem to recall this article was on the list. Don't quote me on that, but I think it is important enough to be worth our time! Thanks, Walkerma 04:27, 12 October 2006 (UTC) Surface tensionYes sure, I can explain everything a bit more and derive the formulae, where should we keep the conversation, in my talk page or in yours?? I really feel that with a little effort and maybe someone else's contributions we could take surface tension up to the good article condition.
