Heating Zinc Oxide
Aim: What change happens when we heat Zinc Oxide?
Equipment:
- Bunsen Burner
- Heat Mat
- Tripod
- Safety Glasses
- Crucible (Small Ceramic Bowl)
- Crucible Holder
- Zinc Oxide
Results:
As it was heating up the colour of the Zinc Oxide turned into a Neon Yellow and then when the powder cooled down it turned into its original colour, White.
When you heat up the Zinc Oxide it loses some of its Oxygen. During this process, Electrons change levels which causes it to change colours.
