Copper and its alloys are relatively soft materials which have a wide range of alloy applications. Preparation Challenge Copper and copper alloys are difficult to prepare because they have a tendency to work harden and have oxide inclusions. The result is that the oxide inclusions can become dislodged and scratch the surface.

This extraction experiment consists of two competition reactions. A metal oxide is reacted with charcoal. If the charcoal carbon is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel. Start with an oxide of lead then observe what happens to an oxide of copper.

Hydrometallurgy is the most common method for the production of copperII oxide. A solution of ammonia and ammonium carbonate in the presence of air effectively leaches metallic copper into solution the solution is stripped of ammonia and carbon dioxide by steam injection or pressuried boiling to produce black copperII oxide.
