Question

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.

Cryolite (Na3AlF6) and fluorspar (CaF2) reduce the melting point of the mixture and increase its conductivity.

Q. Cryolite and fluorspar are mixed with $A l_{2} O_{3}$ during electrolysis for extraction of aluminium to

increase the mass of the reaction mixture

get other products at anode like fluorine

lower the melting point and increase the conductivity of the electrolyte

reduce aluminium oxide by cryolite.

Cryolite $(N a_{3} A l F_{6})$ and fluorspar $(C a F_{2})$ reduce the melting point of the mixture and increase its conductivity.
