Electrolysis Flashcards
1
Q
Where do you purify aluminium oxide from?
A
Bauxite
2
Q
What do you mmix with the Aluminium oxide?
A
Cryolite
3
Q
What does Cryolite do?
A
Lowers the melting point
4
Q
After mixing Aluminium oxide with cryolite what is the next step?
A
Melt aluminium oxide so it is molten
5
Q
Why does the Aluminium oxide need to be molten?
A
So the ions are free to move around
6
Q
What are the electrodes made out of?
A
Carbon
7
Q
What do the two electrodes act as?
A
Conductors
8
Q
Why is a wire connect to the anode and cathode?
A
So the electrons can flow
