उत्तर

The corrosion of copper produces a green coating of basic copper carbonate on its surface.

Explanation:

When a copper object is exposed to moist air for a long time, it slowly reacts with oxygen, carbon dioxide, and water vapour. This oxidation process causes the shiny brown metal to corrode, producing a green layer on its surface commonly called a patina. This green substance is basic copper carbonate, which is a chemical mixture of copper hydroxide and copper carbonate [CuCO3 . Cu(OH)2].
