Electrical Conductivity and Electrolysis

“The decomposition requires more energy input than the heat released by the inverse process (285.8 kJ/mol, or 15.9 MJ/kg).” This is in clear violation of conservation of energy. Perhaps what they intended to say was that electrolytic decomposition is not 100% efficient? Mindyobusiness12 (talk) 13:46, 29 December 2022 (UTC)

Dangers of dihydrogen monoxide

• ... that in the spring of 1997, a 14 year old's school science fair project made an argument to ban a chemical compound named dihydrogen monoxide? Source: Diydrogen monoxide

Created by Chemification (talk). Self-nominated at 06:12, 2 July 2023 (UTC). Post-promotion hook changes for this nom will be logged at Template talk:Did you know nominations/Water; consider watching this nomination, if it is successful, until the hook appears on the Main Page.

• Sorry, Chemification, but the article is not new or recently five-times expanded or newly promoted to Good Article, so it's not eligible. Please see WP:DYK for eligibility requirements and other information about DYK. The article is currently 59,328 prose characters, so a five times expansion is not really possible, but if you get it to Good Article status, you may be able to renominate within a week of that promotion.

Disputed content

The second paragraph in the article as it exists now says the followiing: 'Because Earth's environment is relatively close to water's triple point'. Wander over to 'triple point' and it says that the pressure of water at the triple point is:

'vapor pressure of 611.657 pascals (6.11657 mbar; 0.00603659 atm)'. This is a lot closer to the atmospheric pressure of Mars, and is well below the Armstrong limit.

Water also does not magically change into Nitrogen and Nitrogen into water using some nuclear process either.

Lies sound cool because lying is cool ... NOT. What arguments do people have here that this is not a lie? I think that should be taken out of the article.

"Earth's environment" includes the entire Earth's atmosphere, which definitely has points with pressure below the triple point of water. I can understand your concern if the article stated "Earth's surface" as that would be untrue, and maybe it is worded somewhat confusingly, but as it is right now there's nothing untrue about it.

My dear friend, I feel a tone of aggression in your words, I understand your concern, but you don't need to be so aggressive with your words, be polite, as I'm being with you. (Note: I don’t wanna other discussion, so, get your mood on me, ok?) 177.105.90.20 (talk) 20:39, 26 May 2024 (UTC)

The claim is properly sourced to a university website by an expert. "the Earth environment is close to the triple point and that water, steam and ice can all exist at the surface." and also "Near the surface of the Earth water can exist in three phases - ice (solid), water (liquid), and vapor (steam)". "Relatively close" does not mean that earth is at the triple point. Ramos1990 (talk) 20:56, 26 May 2024 (UTC)

Molecular polarity

• What I think should be changed (format using {{textdiff}}): Under the molecular polarity paragraph it states "oxygen atom retains a negative charge while the hydrogen atoms are positively charged." this is technically wrong it should be a partial negative charge and hydrogen partial positive charge
• Why it should be changed: its wrong
• References supporting the possible change (format using the "cite" button):

"Oxidane"

a link in the infobox for the word Oxidane would be nice (it redirects to a nomenclature section, currently located at Properties of water#Nomenclature, information not currently found in this article). However, looking at how this infobox is configured (pulled through from the chembox template), I'm actually not at all sure how one would go about adding that. So I'm leaving this comment instead --Tomatoswoop (talk) 20:43, 28 June 2024 (UTC)
