- Electrolysis
- Oxidation and Reduction
- OIL RIG
- Oxidation Is Loss
- (of electrons)
- Reduction Is Gain

- OIL RIG
- Splitting by Electricity
- To split aluminium from its ore, you need to add CRYOLITE
- Na3AlF6 = Cryolite
- Reduces the melting point to 700 degrees
- Al3+ ADD 3e- --> Al (Redox)
- 2O2- --> O2 + 4e- (Oxidation)
- 2O2- --> O2 + 4e- (Oxidation)
- To split aluminium from its ore, you need to add CRYOLITE
- Two electrodes in a solution
- + Electrode = Anode
- Negatively charged substance is attracted to the anode
- - Electrode = Cathode
- Positivley charged substance is attracted to the cathode
- Negatively charged substance is attracted to the anode
- Positivley charged substance is attracted to the cathode
- + Electrode = Anode
- Electrolysis is useful for separating substances from unwanted ones
- Aluminium ore - aluminuim
- Salt - Hydrogen, Sodium Hydroxide and Chlorine
- Oxidation and Reduction
