Talk:H₂O

Validity
I see evidence of use as a common noun in English, such as. "glass of H₂O" get no hits, but I think that's because of Unicode and Google issues. Mglovesfun (talk) 15:39, 25 April 2012 (UTC)

Search results are cancelling superscript and subscript formats so you can search with common numbers. When you go through a link, you will see the proper formats, "glass of H₂O", in many results. --Octahedron80 (talk) 05:34, 9 August 2021 (UTC)

Specifically sense 1: "Water as a chemical substance". Duplication of Translingual sense 1: "Water, by its molecular formula..." CitationsFreak (talk) 03:26, 18 November 2023 (UTC)
 * But English is a different "language" than Translingual. I dont think this should be considered duplication. — Soap — 08:49, 18 November 2023 (UTC)
 * If H₂O-the-chemical-formula is translingual, i.e. used across multiple languages, then it definitely is duplication. We don't and wouldn't make sections for H₂O for the tens of other languages where chemistry is written about sufficiently enough. The only argument I see for it are grammatical differences, like the fact that it's uncountable in English whereas that might not be a distinction in other languages, but that falls apart to me pretty fast when you consider that that's the case for just about any chemical formula. There's no separate section for the number 17 in English and German just because one's pronounced sɛvəntiːn and the other ziːptseːn. Delete for me. Hythonia (talk) 12:52, 18 November 2023 (UTC)
