The black substance formed on copper is called copper oxide. It is a chemical compound that forms when copper is exposed to oxygen in the air, resulting in a black or greenish-black tarnish on the surface of the copper.
The black coating that forms on the surface of copper is called copper oxide.
Copper oxide appears as a black or dark brown powder after copper has burned.

When copper carbonate is heated, it changes from its green color to black copper oxide.
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
Cu2O (Copper(II) Oxide) is a Red Powder. CuO (Copper(I) Oxide) is a Black Powder.
