green
Oxygen turns copper green.
copper turns to blue-green copper oxide.
On the copper surface basic copper carbonate is formed.
Copper wiring can turn black due to oxidation, which occurs when the copper comes into contact with air and moisture. This chemical reaction forms a layer of copper oxide on the surface of the wire, giving it a black appearance. It is a natural process and does not affect the conductivity or performance of the wiring.
Copper is a metal that turns green when oxidized.
it's a physical reaction because you can get it back to copper oxide
The color that copper turns when it oxidizes is called verdigris. It is a greenish-blue patina that forms on the surface of copper over time due to exposure to air and moisture.
Copper turns green when it oxidizes because of the formation of a greenish layer of copper oxide on its surface.
Yes it turns green
Physical Changes
It turns greenish.
Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish .
