Make Sb2S3

AlphaDecay - 30-3-2014 at 20:39

Are these reactions possible, to make Antimony Trisulfide?

Sb2O3 + 6H3CCOOH -> 2Sb(H3CCOO)3 + 3H2O
(True according to wikipedia)

2Sb(H3CCOO)3(aq) + 3Na2S(aq) -> Sb2S3(s) + 6NaH3CCOO(aq)
Antimony trisulfide would precipitate out of the solution

Is this possible?

Yes, but... why? Stibnite exists.

I cant find it where I live, so I will have to make it from Antimony trioxide bought from pottery shops

starting 10$, so far no bids, free shipping. 62g so a decent size chunk isn't too hard to find. not saying you shouldn't try to make it, just that it is available if you wanna save the Sb2O3 for something else.

Does Sb2O3 reacts with hydrogen sulfide?

Probably, at elevated temperatures. Not recommended, because antimony compounds are toxic and this would likely occur in the gas phase.

Well,

I found this in a book:
Sb2S3 can be made by:
"Reduction by the use of sulphur in excess upon oxide of
antimony (Jannash and Eemmler) or antimonate (Unger)."

Here it goes the page where it is stated:

Vogel's Qualitative Chemical Analysis suggests that antimony(III) oxide can be dissolved in dilute hydrochloric acid, and hydrogen sulphide will result in an orange-red precipitate of antimony(II) sulphide from solutions which are not too acid. This precipitate is soluble in warm hydrochloric acid.

I cringe at the thought of one grinding up those beautiful stibnite crystals for chemical use D: haha
