This diagram shows the electrolysis of copper chloride.

a i. On a copy of the diagram, mark the direction of the conventional current in the electrolyte. Label it conventional current.

ii. Mark the direction of the electron flow in the connecting wires. Label this electron flow.

b. In a time period of 8 minutes, 3.6 × 10¹⁶ chloride (Cl⁻) ions are neutralised and liberated at the anode and 1.8 × 10¹⁶ copper (Cu²⁺) ions are neutralised and deposited on the cathode.

i. Calculate the total charge passing through the electrolyte in this time.

ii. Calculate the current in the circuit.
