Reduction by Hydrogen 1 of 10 How the melting point of Aluminium Oxide is reduced? Dissolving Aluminium oxide in molten cryolite 2 of 10 Name 3 metals extracted from their ores by reduction by Carbon Iron, manganese and copper 3 of 10 The Equation at the anode of Aluminium Extraction 2O2- → O2 + 4e- 4 of 10 Why is Titanium not extracted by carbon? It forms titanium Carbide which makes it brittle 5 of 10 Disadvantages of using hydrogen to extract tungsten Very expensive and Hydrogen is highly expolsive 6 of 10 Disadvantage of using carbon to extract iron, copper and manganese Produces CO2 which is a greenhouse gas 7 of 10 What is used to extract titanium? Chlorine and carbon, fractional distillation then magnesium or sodium 8 of 10 Equation at the Cathode Al3+ + 3e- → Al 9 of 10 Adavantages of recycling metals Uses less energy therefore less expensive, less landfills needed 10 of 10
