Talk:Limiting reagent

HI... i don't really like stoichiometry...but here it is

"This concept requires nothing" What the hell does that mean?

I don't know what that was supposed to imply, so I removed it. I think it was honestly just someone's arrogance, stating that one would have to be an idiot not to understand it..or that the concept was so basic that it required "nothing" to understand it. Unfortunately, this article should be considered a stub as it does not really cover the subject well at all...and it is....;o

Eh, it gives you the gist of what a limiting reactant is. I mean, it did help me :P

this concept is a pain in the ass lol

this helped alot, thanks —Preceding unsigned comment added by 140.184.58.117 (talk) 00:11, 15 October 2008 (UTC)

Reaction?
I think the featured reaction's balanced equation should be added. I will do so by the end of the month. bombchelle (not logged in)

Formula seems dubious
The provided formula for finding limiting reagents seems to be questionable. From my past experiences, I have used the formula in my chemistry class stoichiometry assignments, only to find out that my answers were incorrect. (To be frank, however, my teacher had made the problems herself, and I can't quite say that she's undoubtedly an expert in chemistry.) I've recently tried searching for an identical or similar limiting reagent formula on the Internet; however, I have found nothing resembling a limiting reagent formula on any site. An attempt to test the formula with an example from SparkNotes also ended with a vastly different (and inaccurate) result from the original problem. Which brings me to my question: is this formula truly reliable for calculating limiting reagents? If so, then where did the formula originate? -69.225.80.183 (talk) 06:02, 27 May 2009 (UTC)

Easier way
In fact, there is an easier way to determine the limiting reagent with the same data and any amount of reagents: $$\frac{\mbox{Moles of Reagent X }}{\mbox{Coefficient of Reagent X}}$$

The reagent that has the lowest answer to this formula is the limiting reagent.

 * Yes, this is the easiest way. At the moment the article is a mess and shows 3 different methods without showing their logical connection, and major revision is needed. This is a 4th method which could be used to construct an article, but one would have to show where it comes from and give examples. Also extra calculation is still needed if one wants to know the excess quantity of the non-limiting reagent(s).Dirac66 (talk) 01:48, 23 April 2010 (UTC)
 * I have now rewritten the article, and included the shortcut suggested by Je007 at the end and shown its relation to the other methods.Dirac66 (talk) 02:53, 18 January 2011 (UTC)

Proposed merge
The new article Excess reagent serves no useful purpose as it is practically identical to this article. The only reason I can see for creating a new article is that this article did not explicitly use the term excess reagent, which was therefore undefined on Wikipedia. However I have now remedied this omission more simply by adding a mention of excess reagent at the end of the first paragraph. So we really don't need two virtually identical articles and I propose to merge them. This means having only this one article named Limiting reagent which now explains Excess reagent also. The new article Excess reagent would be replaced by a redirect, so that any reader who searches for Excess reagent would be automatically redirected to this article.

In accordance with Wikipedia policy (see WP:Merging), I am inviting a discussion on the merge proposal. After a week if there is consensus I will go ahead with the merger. Dirac66 (talk) 03:27, 22 December 2013 (UTC)
 * No response after one week, so I have gone ahead and merged. Dirac66 (talk) 15:02, 29 December 2013 (UTC)

limiting agent
With regard to the removal of the term "limiting agent",, I present the evidence below that the term
 * is valid,
 * is sometimes used in technical and non-technical context, and
 * should be included in the article.

By ACS search
 * "limiting reagent" = 2658
 * "limiting reactant" = 1072
 * "limiting agent" = 97

By google search
 * "limiting reagent" about 774,000 results
 * "limiting reactant" about 446,000 results
 * "limiting agent" about 13,700 results

 * No response after one week, so I have put the term back into the article. --Taweetham (talk) 05:32, 1 January 2019 (UTC)
