Use
When heated in air, copper(I) sulfide oxidizes forming copper(II) oxide, and sulfur dioxide: Cu2S + 2O2 2CuO + SO2 Heating in the absence of air produces copper(II) sulfide and copper: Cu2S CuS + Cu When heated with nitric acid, copper(I) sulfide decomposes forming copper nitrate and hydrogen sulfide. The compound dissolves in aqueous solutions containing cyanide ions forming soluble copper-cyanide complexes. Copper(I) sulfide reacts with polysulfide anions in aqueous solutions forming soluble copper polysulfides.
