Demonstrate the practical or do a 'follow with me' step-by-step method. If you are short on time you could just carry out the first part of the practical to produce the copper sulfate solution then stop.

Keywords

Metal oxide - consists of metal atoms bonded to oxygen atoms.
Adding to excess - when a reactant is present in a greater amount than is necessary to completely react.
Non-metal oxide - consists of non-metal atoms bonded to oxygen atoms.

Non-metal oxides placed in water cause a reaction. To avoid teaching another reaction at this stage, refer to, and label, the solutions as non-metal oxides in water and use dilute solutions of HNO₃, H₂SO₄ and H₃PO₄. The acidity of the oxides could be linked to environmental issues such as acid rain.
