== Scientific names of water ==
Some time ago [[https://en.wikipedia.org/w/index.php?title=Dihydrogen_monoxide_hoax&diff=next&oldid=612156674 this edit]] removed explication of the nomenclature used to derive the term dihydrogen monoxide. I wonder if anyone else thinks there is value in restoring any or all of the explication of the scientific naming conventions which are the origin of the name DHMO. Numerous sources were cited, so calling it original research is not quite accurate, is it? --[[User:JimWae|JimWae]] ([[User talk:JimWae|talk]]) 07:30, 25 April 2015 (UTC)

Version by GenQuest

I am not sure that the wholesale revert was warranted. While I agree that GenQuest's intro is rather clumsy, the rest of the text is IMO better structures and has additional facts. I'd rather rewrote once more than revert the whole new text. Staszek Lem (talk) 01:42, 17 June 2014 (UTC)[reply]

Sorry, I responded on my talk page - feel free to revert by revert and/or edit it. I may have become jaded about this article for obvious reason and over-reacted (although GenQuest's intro is pretty hard to read). - DavidWBrooks (talk) 17:06, 17 June 2014 (UTC)[reply]

Not a hoax

Dihydrogen monoxide is just the name for water, and all the claims are real facts. Editor abcdef (talk) 08:12, 2 September 2014 (UTC)[reply]

That's right. The hoax was using these facts to convince people that there was a lurking danger that needed to be addressed. Mindmatrix 13:20, 2 September 2014 (UTC)[reply]
Everything has its dangers, they all needed to be addressed. Editor abcdef (talk) 05:54, 3 September 2014 (UTC)[reply]
See the lengthy discussions on this very topic above. --— Rhododendrites talk13:29, 25 September 2014 (UTC)[reply]

Chemtech article circa 1984

The journal CHEMTECH did an article in the same vein in (I believe) 1984. I used it in my Pchem classes as a graduate student. It included such information as LD50 values (listed in depth in inches) for various animals, including 'cat in bag with rock'. — Preceding unsigned comment added by 98.232.217.136 (talk) 17:35, 3 April 2015 (UTC)[reply]

DHMO

I dont know how many people come here when they're trying to find "Dental Health Maintenance Organization". I, though familiar already with the dihydrogen monoxide story, was surprised to find not even a mention of the other meaning. Is it worth making a dab page just for that ? Soap21:20, 22 April 2015 (UTC)[reply]

If there are high hits for Dental Health Maintenance Organization, the most that should be done is a simple disambiguation. Even IF the confusion is significant, unless we garner secondary sources (highly unlikely that someone will make a news article on it), we can't do Original Research, especially on something Self referencing.

Scientific names of water

Some time ago [this edit] removed explication of the nomenclature used to derive the term dihydrogen monoxide. I wonder if anyone else thinks there is value in restoring any or all of the explication of the scientific naming conventions which are the origin of the name DHMO. Numerous sources were cited, so calling it original research is not quite accurate, is it? --JimWae (talk) 07:30, 25 April 2015 (UTC)[reply]

Various names for water are commonly used within the scientific community. Some such names include hydrogen oxide, as well as an alkali name of hydrogen hydroxide, and several acid names such as hydric acid, hydroxic acid, hydroxyl acid, and hydroxilic acid. The term "hydroxyl acid" used in the original hoax is a non-standard name. An additional name, μ-oxido dihydrogen, has been developed for this compound.[1]
Under the 2005 revisions of IUPAC nomenclature of inorganic chemistry, there is no single correct name for every compound.[2] The primary function of chemical nomenclature is to ensure that each name refers, unambiguously, to a single substance. It is considered less important to ensure that each substance should have a single name, although the number of acceptable names is limited.[2] Water is one acceptable name for this compound, even though it is neither a systematic nor an international name and is specific to just one phase of the compound. The other IUPAC recommendation is oxidane.[3]
The use of numerical prefixes is typical nomenclature for compounds formed by covalent bonds, which are present in water.[4][5] The prefix for the first named element is often dropped if the elements involved commonly form only one compound, or even if the number of atoms of the first-named element is the same in all the compounds of the two (or more) elements.[6] Thus H2S is often simply called hydrogen sulfide, and lithium oxide is a common name for Li2O. However, the names dihydrogen sulfide,[7] dilithium oxide,[8] and dilithium monoxide[9] are also commonly used both in industry and in universities, even though Li2O is ionic.
The "mono-" prefix is often dropped for the second-named element if it is the only common compound the elements form.[10] Thus for instance the IUPAC name of H2S is hydrogen sulfide rather than hydrogen monosulfide.[11] However, since carbon and oxygen can form several compounds (carbon monoxide, carbon dioxide, tricarbon dioxide, and dicarbon monoxide), the mono- prefix is kept, as it is with silicon monoxide and silicon dioxide. Indeed, hydrogen and oxygen do form another common compound, H2O2 (hydrogen peroxide). Using prefix nomenclature, H2O2 would be called dihydrogen dioxide. Thus, keeping the "mono-" in dihydrogen monoxide could in principle serve to distinguish it from another compound.
