Note when writing equations the reactants should be on the left hand side of the arrow and the products should be on the right hand side of the arrow but this is hard to do on this software.

  1. Stand the tube in a 150 cm3 beaker, half-filled with just-boiled water from a kettle.

  2. Add a small spatula of copper (II) oxide to the acid.

  3. Leave to warm for 2-3 minutes.

  4. Firstly Measure 20 cm3 (using a measuring cylinder) of 0.5 M sulfuric acid into a boiling tube.

  5. Filter the contents of the boiling tube into the crystallising dish.

  6. Agitate gently then put tube back into the hot water. Repeat step 4 and 5 until residue remains.

  7. Rest a filter funnel in a 100 cm3 conical flask. Place a folded paper in the funnel.
