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.
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.
Keywords
