- dilute
- sulfuric acid
- 50mL measuring cylinder
- two 100 mL beakers
- Bunsen burner
- tripod
- gauze mat
- funnel
- filter paper
Method:
- Add 20 mL of sulfuric acid to a 100mL beaker. Heat the acid until it reaches 70 C Turn off your bunsen burner.
- Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker.
- Repeat step 2 until no more will dissolve.
- Fold the filter paper and place it in the funnel.
- Make sure the beaker is cool enough to hold at the top.
