there is disappearance of the colour blue and formation of a black colour precipitate
Explanation:
- due to this chemical reaction. copper sulphate solution is usually blue in colour. When hydrogen sulfide gas which has a rotten egg smell is passed through the solution then there is formation of copper sulphide.
- copper sulphide is usually black in colour and hence it forms a precipitate which settles at the bottom of the container. The balanced chemical reaction is: CuSo4 + H2S (g) = CuS + H2SO4
