Talk:Ammonium sulfate

message: If it is a start-class page why not add also the lab prep? Don't get me wrong but ... rather than a class lesson it sounds like teaching the biggest chem industry engs of tomorrow. Come on ...
Simply "Ammonium sulfate can be made in the laboratory by neutralising dilute sulfuric acid with ammonia solution.
H2SO4(aq) + 2NH3(aq) -> (NH4)2SO4(aq)  
As already stated below - not only the end - but the entire project may desperately need some kind of robust cleaning and categorization.

message: Mohr´s salt is the double sulfate of ammonium and iron (II) (it´s a schönite),not the ammonium sulfate.
I just reverted spelling changes by an anon and an undiscussed move to ammonium sulphate. Sulfate is the IUPAC standard and the spelling of preference for Wikipedia science and chemistry articles. Vsmith 23:37, 4 December 2005 (UTC)

message: Does anyone know whether "gas-works" in this article, under the commercial production section, means the refining of natural gas as an energy source, or gas as in petrol, petroleum, gasoline?

message: ammonium sulfate is NOT 18% sulfur as stated on this page.  It is 24% sulfur:
2N+8H+1S+4O=(2*14)+(8*1)+(1*32)+(4*16)= 132 atomic weight of (NH4)2 SO4 ammonium sulfate.
Sulfur's atomic weight of 32 divided by 132 = 24%, NOT 18%.  Also, see http://www.sulfn.com/68.119.21.47 15:58, 1 September 2006 (UTC)

message: This data is inaccurate.  Pure compounds do not melt over a
wide span 235-280.  The correct data is
Melting point 235 degrees C
Start of Decomposition 280 degrees C

message: I doubt the substance is hygroscopic. My personal experience with the salt is not. I have successfully kept it in a vial for over 25 years, and the substance is perfectly dry. Also, the CRC handbook does not say it's hygroscopic. Neither does Handbook of Inorganic Chemicals from Pradyot Patnaik, from which the text here at wiki has been largely taken.

message: I see this in the article
Heating at higher temperature result in fully decomposition into ammonia, nitrogen, sulfur dioxide and water.
Should this really say sulfur trioxide not sulfur dioxide?  Jokem (talk) 01:41, 18 August 2011 (UTC)

message: I am confused by the inclusion of a density for ammonium sulfate at 20 C. As it is a solid at this temperature, density depends on packing, and its inclusion here will likely just confuse the reader. Ggspring (talk)Greg

message: I got here from a redirect from "Dolamin". I'm looking for information on a medication called Dolamin Flex, the box says the active ingredients are cyclobenzaprine hydrochloride and lysine clonixinate. Is that related to what is described in this article at all? --TiagoTiago (talk) 08:06, 15 February 2014 (UTC)

message: This material is cited to be H315, H319 and H335, yet has pictogram GHS09 which is attributed to aquatic toxicity. There is an ECHA dossier for this material that states that it is not classified at all. I also have access to several SDS for this material that also state that it is not classified under GHS/ CLP. I believe that this classification is wrong for this material and CAS number.  — Preceding unsigned comment added by 80.209.167.52 (talk) 12:55, 17 June 2021 (UTC)
