Lesson details
Key learning points
- A metal oxide consists of metal atoms bonded to oxygen atoms.
- Metal oxides are bases and can react with acids to neutralise them.
- Metal oxide + acid ⭢ metal salt + water
- A non-metal oxide consists of non-metal atoms bonded to oxygen atoms.
- Non-metal oxides in water make acidic solutions.
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.
Common misconception
Pupils find it difficult to carry out a complex 3-stage practical.
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.
Equipment
Heat resistant mat, Bunsen burner, gauze, tripod, beaker, spatula, stirring rod, conical flask, filter paper, funnel, evaporating basin, copper oxide, sulfuric acid.
