Extraction of Copper from Copper Oxide
In experiment C1.5.1.1, charcoal is the reducing agent to reduce tenorite (CuO) to elementary copper. When heated, the mixture of tenorite and pulverised charcoal produces red copper and carbon dioxide. A saturated calcium hydroxide solution is used to verify the presence of the carbon dioxide.
