Is calcium sulfide soluble in water? : r/chemhelp - Reddit
2020年9月22日 · I am surprised that sulfide wasn't there; it is commonly listed. Sulfides are commonly insoluble (except for the ones with alkali metal cations, of course). Also, the +2 -2 charges lead one toward suspecting poor solubility. Ca salts are often insoluble; sulfides are often insol. CaS? (Actually it is a bit more complex, in how it reacts with water.

Neutralizing Hydrogen Sulfide with Calcium Nitrate
2023年6月27日 · If so, the hydrogen sulfide will get oxidized to harmless sulfates, some of which may precipitate as calcium sulfate (aka gypsum). You may get minute amounts of elemental sulfur, but I doubt it will be an issue. Nitrates should get converted to N2, though judging by this paper, it's possible you'll get a little bit of nitrites alongside:

Is there a way to extract sulfuric acid from calcium sulfate?
As for the chemical processes, calcium sulfate can be pyrolyzed into calcium oxide and sulfur(VI) oxide, and then use the latter to form sulfuric acid. That, however, occurs at temperatures well above 1200 °C, which causes significant decomposition of sulfur(VI) oxide into …
