Answer:
hen copper vessel is exposed to moist air for a long time it develops a green layer on its surface. Copper corrodes by oxidation in which it reacts with oxygen in the air to form copper oxide. Copper oxide then combines with carbon dioxide to make copper carbonate, which gives it a green colour.

Answer:
Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide.
The chemical reaction is
2Cu + H2O + CO2 + O2 → Cu(OH)2 + CuCO3
