Question 1 · 1 mark · Difficulty 1/3

At a bauxite processing plant in Jamaica, aluminium is extracted by electrolysis of molten aluminium oxide. At which electrode is aluminium produced?

  1. Anode
  2. Cathode
  3. Both electrodes
  4. Neither electrode
Show answer & explanation
✓ Answer: BCathode
Award 1 mark for identifying that aluminium (a metal) is produced at the cathode by reduction. A is incorrect — oxygen is produced at the anode by oxidation. C is incorrect — different products form at each electrode. D is incorrect — aluminium is definitely produced during electrolysis.
Question 2 · 1 mark · Difficulty 1/3

Which of the following substances will NOT conduct electricity when molten?

  1. Sodium chloride
  2. Lead(II) bromide
  3. Sugar
  4. Potassium iodide
Show answer & explanation
✓ Answer: CSugar
Award 1 mark for identifying that sugar is a covalent compound and does not form ions when melted. A is incorrect — NaCl is ionic and conducts when molten. B is incorrect — PbBr₂ is ionic and conducts when molten. D is incorrect — KI is ionic and conducts when molten.
