Copper sulfide (CuS) is black in color.
Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper(II) sulfate. Remember that Copper sulfate contains Copper, Sulfate and Oxygen because anything ending with 'ate' therefore contains oxygen
The reaction between CuCl2 (copper(II) chloride) and H2S (hydrogen sulfide) is a double displacement reaction. The balanced chemical equation is: CuCl2 + H2S -> CuS + 2HCl The products formed are CuS (copper(II) sulfide) and 2HCl (hydrochloric acid).
Copper sulfide is a compound that can exist in various forms, such as CuS, Cu2S, and Cu5S4. It is insoluble in water and can be either black or brown in color. Copper sulfide is used in the production of semiconductors, pigments, and as a source of copper in metallurgy.
Digold sulphide, Au2S: black-brown Digold trisulphide, Au2S3: brown-black to black
Copper(II) sulfate has the formula CuSO4.

The name of the chemical compound CuS is copper (II) sulfide.
No, CuS (copper sulfide) is not an electrolyte. Electrolytes are substances that dissociate into ions in solution to conduct electricity, while CuS remains intact as a solid compound.
