Question 1 · 1 mark · Difficulty 1/3

Electrolysis is the breaking down of a substance using:

  1. Electricity
  2. Heat alone
  3. A catalyst
  4. Light
Show answer & explanation
✓ Answer: AElectricity
Electrolysis uses an electric current to break down an ionic compound (the electrolyte) into its elements.
Question 2 · 1 mark · Difficulty 2/3

Why must an ionic compound be molten (or dissolved) for electrolysis?

  1. So the ions are free to move and carry charge
  2. So it gets hotter
  3. So it becomes a gas
  4. So it dissolves the electrodes
Show answer & explanation
✓ Answer: ASo the ions are free to move and carry charge
In the solid the ions are fixed; melting (or dissolving) frees the ions so they can move to the electrodes and conduct charge.
