PubChem Id
editSomeone should please check the given PubChem Id (currently 237873) - it points to Na2HS. Probably PubChem entry 14804 (Na2S) fits better!? NE5147-1202 (talk) 06:14, 25 April 2012 (UTC)
Chembox
editIs the image OK?--Wickey-nl (talk) 14:45, 24 July 2010 (UTC)
- It has an antifluorite structure, so the fluorite image works well for this any many related materials. Alkali metal oxides are the same, I think. The main message we aimed for was that readers understand that S2- only exists in the solid, and virtually no where else.--Smokefoot (talk) 14:54, 24 July 2010 (UTC)
Japanese Suicuides
editYou guys feel the Japanese suicide epidemic caused by inhaling sodium sulfide should have a section in the article? It's the only reason I know what sodium sulphide is and why I came to this page —Preceding unsigned comment added by 123.243.155.250 (talk) 15:16, 4 December 2010 (UTC)
- Sure thing, just provide some references when you write the section and follow Wikipedia Manual of style bcartolo (talk) 13:12, 28 May 2012 (UTC)
- Probably not a big deal. It's trivia in my book - 99.99999% is used for other purposes. A sentence in the safety section.--Smokefoot (talk) 13:28, 28 May 2012 (UTC)
Phase diagram
edithttps://www.sciencedirect.com/science/article/pii/S0040603102001582
phase diagram of SodiumSulfide and water. Shows Eutectic freeze below 0degC at 10%conc. then 50 and 100. well 100degC is boil...
Wikistallion (talk) 15:48, 22 April 2018 (UTC)
Freeze minimum around -10degC at chemically 45hydrate. 2.1%mol Na2S which is physical mix of H2O and Xhydrate.phase. the nonahydrate doesnt properly show.
Then at 10% mol Na2S melt almost 100degC max nonahydrate (?) with 80degC eutectic minimum at 1/15 mol phasemix. that then probably IS the nonahydrate and pentahydrate. but pentahydrate Melt seems to be at 200degC...
h2O then evaporates above that.
Any scientist, repeat that under geological pressure to find melt of Trihydrate etc. in phasediagram.
Same thing runs on Na2S - S phase diagram. is also available. there actual Na4S or Na6S under pressure? thats high pressure sulfide variants. do they exist? Wikistallion (talk) 16:19, 22 April 2018 (UTC)
Assume Temperature say 80degC. there would be TWO different Melt points. One gets pentahydrate and dekahydrate. Thats Eutectic solidification. Concentration of solution determines actual mass ratio of the two phases.
Same at 0..-10: also solidification of 2phases. cooling down from 70degC yields jzst pentahydrate crystal. Or different higher hydrate say 21hydrate? thats how this works Wikistallion (talk) 16:51, 22 April 2018 (UTC)
Discrepancies

Dr Scholl's?
editI removed this statement but maybe its true: "Sodium sulfide is the active ingredient in Dr. Scholl's ingrown toenail pain treatment."--Smokefoot (talk) 04:29, 1 August 2024 (UTC)
