What you'll learn
Chemicals in the environment and extracting metals.
Key ideas
- Ions in sea water; ionic compounds conduct when molten/dissolved.
- Electrolysis and metal extraction (reactive metals by electrolysis, others by carbon).
Exam tips
- Link a metal's reactivity to its extraction method.
- State when ionic compounds conduct electricity.
Common mistakes
- Extracting reactive metals with carbon.
- Saying solid ionic compounds conduct.
