Extracting metals with charcoal | Experiment | RSC Eduion

In this experiment, students heat two metal oxides with powdered charcoal. If the carbon is more reactive than the metal it will remove the oxygen from the metal oxide and leave traces of the metal in the reaction vessel. Students try lead(II) oxide first, before using a slightly modified technique to try copper(II) oxide.
