thread_title: State of matter Marking

message: I'm going to try and overhaul this article to be clearer, as well as expand what is presented. I've already started deleting the how-to information presented. I plan on providing some graphics to explain the parts of a chemical equation among other plans. Chemeditor (talk) 23:28, 6 October 2008 (UTC)
thread_title: Overhaul of article

message: I propose merging Ionic equation into a subsection of the chemical equation article because ionic equations really are just a subset of the more general idea of chemical equations. Considering the limited information presented in both articles, it would be best to combine them. Chemeditor (talk) 22:54, 5 October 2008 (UTC)
replies: text: I also suggest adding Molecular equation into the main article for the reasons above. Chemeditor (talk) 23:03, 5 October 2008 (UTC)
replies: text: I've gone ahead and merged the two other articles into this one.  Chemeditor (talk) 02:33, 10 October 2008 (UTC)
thread_title: Merger with Ionic/Molecular Equation

message: I'm concerned about this article because it reads like a how-to guide and Wikipedia directives explicitly state that Wikipedia is not supposed to be a how-to guide.  Perhaps we can clean this up? -SocratesJedi | Talk 03:48, 28 January 2007 (UTC)
thread_title:  Wikipedia is not a how-to 

message: They seem to share the same scope. Maybe we should merge them? P3net 00:14, 7 March 2007 (UTC)
thread_title: Merge with Chemical Formulas

message: maybe you can add the identifications of the different symbols used in solving chemical equations? that will be a big help... thanks  —Preceding unsigned comment added by 124.107.87.250 (talk) 02:48, 25 November 2007 (UTC)
thread_title:  chemical equations 

message: The article doesn't explain what the state symbols mean, it just jumps into using them. The symbols I'm talking about are: (aq),(I),(S), ... etc...
Like: AgCl(s)  I remember that (aq) means aqueous, but its been a while since I took chemistry and don't remember the others.75.82.133.73 (talk) 12:28, 18 October 2008 (UTC)
thread_title:  State Symbols 

message: Are any of them viable per WP:EL? Looks to me like just a bunch of random "yet another" teaching/practice-problems or reaction-balancing applets. Might be a good pile for DMOZ, but not here IMO. DMacks (talk) 21:50, 2 February 2009 (UTC)
thread_title:  External links 

message: In the net ionic queation example, the precipitates is marked as solid (s), but the ions aren't marked as aqueous (aq). As my current chemistry proffesor keeps reminding me, a chemical equation must have all chemical states labeled "or it's wrong." I'm not sure if that is his opinion on the matter (no pun intended), or if he's trying to teach the scientific standard. Could an expert check this? NickNackGus (talk) 23:08, 8 October 2012 (UTC)
replies: text: I cannot find that requirement in anything authoritative, such as IUPAC rules. But your textbook might include it as a best practice or in the context of learning about the nature of the chemical changes (up through intro-college level), and therefore your professor might require it when grading assignments on those topics. It is an explicit indication of more of the changes that is occurring (not just the ions combining and becoming a solid result, but also that they become desolvated). "The physical state of chemicals is also very commonly stated in parentheses after the chemical symbol, especially for ionic reactions" (emphasis mine). I added a comparative example to the article.
