Teaching Chemical Tests: Ions and Gases in GCSE Chemistry

Pupils learn the tests for hydrogen, oxygen, carbon dioxide and chlorine, identify metal ions from flame test colours and the colours of hydroxide precipitates, and test for carbonate, halide and sulfate ions. Detective-style questions ask them to combine results to identify unknown compounds such as sodium chloride and iron(III) sulfate.

• Describe the tests for hydrogen, oxygen, carbon dioxide and chlorine.
• Identify metal ions from flame test colours.
• Identify metal ions from the colour of hydroxide precipitates.
• Describe the tests for carbonate, halide and sulfate ions.
• Combine test results to identify an unknown compound.
