3 key facts to remember about electrolysis of aluminium:
1- Positive aluminium ions are attracted to the negative cathode while positive oxide ions are attracted to the positive graphite anode.
2- At the anode, the oxide ions react with the graphite to make carbon dioxide - this means the anodes need to be replaced constantly.
3- The aluminium ore is purified and dissolved in molten cryolite - this is cheaper than melting the ore itself.
