Chemistry: Year 10 Term 1: Extraction of Aluminium

Name 3 uses of aluminium (3)
Pans; Car bodies; Power cables
1 of 11
How reactive is aluminium? (1)
Quite reactive
2 of 11
What does this mean in terms of extraction? (2)
It cannot be displaced using carbon so electrolysis must be used
3 of 11
What is the ore of aluminium called and what does it contain lots of? (2)
Bauxite, Al2O3 (aluminium oxide)
4 of 11
To melt Al2O3 what must be added to it to reduce the melting point? (1)
Cryolite
5 of 11
Why is this useful? (2)
Reducing the melting point reduces the energy required
6 of 11
What forms at the cathode? (1)
Aluminium
7 of 11
What forms at the anode? (1)
Oxygen
8 of 11
Where is the Al collected and why? (2)
At the bottom as the bottom lining of the cell is negative
9 of 11
What is oxidised/reduced in the electrolysis of Al2O3? (2)
Al - reduced; O - oxidised
10 of 11
The anodes are made of what, producing what gas? (2)
Carbon, CO2
