2. Apron
3. Spoon
4. 150ml Beaker
5. Liquid Z
6. Liquid Y
7. Crystal X
8. Stirring Rod
9. Foil
10. Graduate Cylinder 50 ml
Procedure: (See lab sheet)
Procedure Number Observation
3 Nothing significant, crystal X slowly dissolving, Liquid Y turning a shade of aqua blue
6 Foil is absorbing the liquid, edges of the foil starts to turn red, oxidation
