Cryolite and fluorspar are mixed with Al2O3 during electrolysis for extraction of aluminium to
A
Increase the mass of the reaction mixture
B
Get other products at anode like fluorine
C
Lower the melting point and increase the conductivity of the electrolyte
D
Reduce aluminium oxide by cryolite
Answer
Lower the melting point and increase the conductivity of the electrolyte
Explanation
Solution
Cryolite reduces the melting point of the mixture and increases its conductivity.
