Question 1 · 1 mark · Difficulty 2/3

Aluminium is extracted from its ore by electrolysis because aluminium is:

  1. More reactive than carbon
  2. Less reactive than carbon
  3. A non-metal
  4. Found as the pure metal
Show answer & explanation
✓ Answer: AMore reactive than carbon
Aluminium is more reactive than carbon, so it cannot be extracted by carbon reduction; electrolysis of molten aluminium oxide is used.
Question 2 · 1 mark · Difficulty 2/3

Electrolysis of aluminium oxide uses a lot of energy mainly because:

  1. A high temperature is needed and large currents are used
  2. Aluminium is cheap
  3. It happens at room temperature
  4. No electricity is needed
Show answer & explanation
✓ Answer: AA high temperature is needed and large currents are used
Melting the oxide/cryolite and passing a large current both require a great deal of (expensive) electrical energy.
