There seems to be a problem in defining what ammonium carbonate really is. If you go out on the web looking for ammonium carbonate you get all sorts of results. Some refer to it as a specific chemical, some say that it is a mixture of chemicals. Those that refer to it as a mixture do not even agree as to the constituents or the proportions. What is sort of serious about this situation is that on most of the sites I have read there is no indication that there are multiple definitions of ammonium carbonate. It is very possible to be looking for one and find a web site that has information on the other and I would never know it. I do not have the chemical expertise to sort all this out but I have found out a few things.
I have found two CAS numbers for ammonium carbonate. There may be more than two but the ones that I found are 10361-29-2 and 506-87-6. The first appears to refer to what this article refers to as "ammonium sesquicarbonate" which is a mixture of chemicals. The second seems to correspond to what in the article is called "normal ammonium carbonate", (NH4)2CO3. I have no idea what is going on here. Can one name refer to two chemicals? Are the the same somehow?
I am hoping some expert can help out here.

similar to the ammonium bicarbonate article, a more detailed history of ammonium carbonate's role as a leavener would be interesting and relevant. The term baking ammonia seems to be applied to both compounds, but specific details about the history of either compound are hard to come by. Buddy431 ( talk) 22:44, 31 July 2008 (UTC)

Although it may be interesting for experimental purposes the manufacturing process described seems historic. Also, I have learnt that there is no true ammonium carbonate but that ammonium carbamate would form. Later I think I have seen both compounds listed as separate products from a major German chemical company. What's the relation between the different compounds. Also I think a decomposition temperature is lacking in the article. —Preceding unsigned comment added by 150.227.15.253 ( talk) 20:15, 13 May 2011 (UTC)
I cannot see the direct relation to Sal Ammoniac that requires the link to the page in the See also section.
Sal ammoniac, the mineralogical form of ammonium chloride
While they are ammonia compounds used in food preparation I cannot see any other link and it was confusing me, there is also a strange statement about using Sal ammoniac as a raising agent that may easily be an error as I have not read that it would decompose. I have left a note on the talk page there as well.

That is unbalanced. If it degrades into CO2 and NH3, then H2O is also produced. . BGriffin ( talk) 03:00, 2 August 2017 (UTC)BGriffin

Shouldn't it be in a different section, or a section all on its own. Also, detail on the production process (equations, reaction mechanisms) would be lovely. — Preceding unsigned comment added by Epictitus ( talk • contribs) 15:59, 13 March 2021 (UTC)
