The balanced chemical equation for this reaction is CuNO3(aq) + K2S(aq) -> Cu2S(s) + 2KNO3(aq). When aqueous solutions of copper(1) nitrate and potassium sulfide are mixed, a double replacement reaction occurs, forming insoluble copper(1) sulfide precipitate. This is a precipitation reaction where the insoluble product is separated from the solution.
Formula: Cu+
Cu2S.
Copper(I) oxide - Cu2O - is the mineral cuprite.Copper(I) chloride - CuCl - is the mineral nantokite.Copper(I) sulfide - Cu2S - is the mineral chalcocite.
The formula for copper(I) chloride is CuCl, and the formula for copper(II) chloride is CuCl2. In copper(I) chloride, copper has a +1 oxidation state, while in copper(II) chloride, copper has a +2 oxidation state.
