Why does copper turn green?
Question asked by: knowitall
Copper turns green because it reacts with oxygen in the air over a long period of time, even though it is relatively inert for a metal.
The green colour is copper carbonate and is often called verdigris.
Pure copper is an excellent conductor of electricity and also relatively cheap - hence about half of the copper produced in the world ends up being used by the electrical industry in one form or another.
