Aluminium is obtained by electrolysis of a molten mixture that contains aluminium oxide. In a similar process, magnesium is obtained by electrolysis of a molten mixture that contains magnesium chloride. Which statement about this electrolysis is correct?
- AChloride ions travel to the anode and are oxidised to chlorine gas.
- BChloride ions travel to the anode and are reduced to chlorine gas.
- CChloride ions travel to the cathode and are oxidised to chlorine gas.
- DChloride ions travel to the cathode and are reduced to chlorine gas.
