Heating Zinc Oxide

Aim: What change happens when we heat Zinc Oxide?

Equipment: Bunsen Burner, Heat mat, Tripod, Safety Glasses, Crucible, Crucible Holder, Zinc Oxide

Results: The Zinc Oxide got heated up it turned yellow but when the heat was turned off it turned white again.

Discussion: When Zinc Oxide heated up it loses its oxygen by the heat and most of the heat is removed from the Oxide, the electrons for the Zinc move to the next level making it change colour. meaning the oxygen atoms are removed but once the heat is gone the oxygen in the air will come back into the Zinc changing the colour back to white again.
