Tarnishing in copper is similar to rusting in iron. It's an electrochemical interaction between molecules on the surface of the metal and molecules in the surrounding air. This interaction forms a layer of chemical compounds over the metal that have a different color from the metal itself.uzzing Surface. Electrochemical interactions take place when molecules of different substances exchange ions in solution. In the case of copper tarnish, the solution is the thin film of condensation that forms on the metal's surface in humid air.
