can i make hydrogen sulfide by reacting a sulfide with oxalic acid? Answered
hi, i am trying to make hydrogen sulfide for the purpose of reacting it with ammonium hydroxide to create ammonium sulfide.
however, since my parent think that concentrated hydrochloric acid is too dangerous to work with, especially since i can only get huge 20L bottles of it, i have decided to quest for a new acid to react with calcium polysulfide, to get hydrogen sulfide, thats when i came across solid oxalic acid.
at first glimps, i saw that it said, hazardous, extremely corrosive acid, i thought "yes", this would work, i could react this with the lime sulfur , but then after some research i discoverd that no-one in the history of the world has ever documented the practical reaction of oxalic acid with a sulfide, in order to make hydrogen sulfide.
so i want to ask , will oxalic acid, when mixed with calcium polysulfide, generate hydrogen sulfide?
another reason though i might point out why i dont think oxalic acid will react with calcium polysulfide, is because it is a solid crystal acid, one that does not evapourate into gas like sulfuric or hydrochloric acid, and i cannot find anywhere documented either of non gaseous acids being able to react with calcium sulfide to make hydrogen sulfide, according to what i have found out, only nitric, sulfuric and hydrochloric acids will work. but this is also the reason i want to use oxalic acid over hydrochloric because i want to boil off the hydrogen sulfide through a tube and into concentrated ammonium hydroxide, but if there is hydrochloric acid in the solution, it would very likely boil off as well, which would be something of a hassle.
