Experimental chemistry topic check
Check G2 Chemistry apparatus choices, gas collection, separation and purity, then practise experimental reasoning alongside supervised practical work.
Learning goals
- Name apparatus for measuring time, temperature, mass and volume, including burettes, pipettes, measuring cylinders and gas syringes
- Suggest suitable apparatus for simple experiments, including collecting gases
- Describe separation and purification using a suitable solvent, filtration, and crystallisation or evaporation
- Describe separation by distillation and fractional distillation
- Describe separation by paper chromatography
- Suggest how to separate and purify a mixture of solids from information about its substances
- Suggest how to separate and purify a solid–liquid mixture from information about its substances
- Suggest how to separate and purify a mixture of miscible liquids from information about its substances
- Interpret paper chromatograms by comparing them with known samples
- Deduce a substance's identity and purity from melting and boiling point data
- Choose and use suitable techniques, apparatus and materials
- Take readings and record observations in experiments
- Interpret and evaluate data and observations from experiments
- Evaluate an experimental method and suggest improvements
