Drugi mogući odgovor:
5. evaporate water
until no more reacts
6. leave to dry
2. Stir to react
4. filter
1. add copper oxide
3. add more copper oxide

Add a small spatula of copper (II) oxide to the acid.
Stand the tube in a 150 cm3 beaker, half-filled with just-boiled water from a kettle.
Agitate gently then put tube back into the hot water. Repeat step 4 and 5 until residue remains.
Filter the contents of the boiling tube into the crystallising dish.
Rest a filter funnel in a 100 cm3 conical flask. Place a folded paper in the funnel.
Leave to warm for 2-3 minutes.
Firstly Measure 20 cm3 (using a measuring cylinder) of 0.5 M sulfuric acid into a boiling tube.
