What you'll learn
Extracting metals and reversible reactions.
Key ideas
- The reactivity series; extraction by carbon or electrolysis.
- Displacement reactions; reversible reactions and equilibrium.
Exam tips
- Link reactivity to extraction method.
- Recognise the ⇌ symbol for reversible reactions.
Common mistakes
- Extracting reactive metals with carbon.
- Ignoring that equilibrium needs a closed system.
