When we keep copper in open air a green layer covers the shining brown surface of the copper because -

• There is plenty amount of carbon dioxide gas present in our atmosphere which reacts with the external copper surface.

• In this chemical reaction,a green coloured chemical substance is produced which is also known as the copper carbonate.

• The production of this copper carbonate turns the shining brown copper into pale green.

Chemical reaction :

2 Cu + 3 CO2 = 2CuCO3 (green)
