#### Oxidation and Reduction - Purdue University

When copper is heated over a flame, for example, the surface slowly turns black as the copper metal reduces oxygen in the atmosphere to form copper(II) oxide. If we turn off the flame, and blow H 2 gas over the hot metal surface, the black CuO that formed on the surface of the metal is slowly converted back to copper metal.
