Is there a way to convert oxide to sulfide

 

Thanks

Dissolve in HCl (forms a soluble chloro-stibnate (III) complex) and slowly add an excess of sodium sulfide while stirring constantly. The nice orange/red precipitate of Sb2S3 separates from the liquid.

 

Do this experiment in a good fumehood or outside. A lot of free H2S is formed as well!

If you are trying to obtain Sb2S3, just go out and purchase the mineral Stibnite (a lot of it comes from Romania).
