In what way is cryolite (Na₃AlF₆)used in the production of aluminum? A) Cryolite is a catalyst,it increases the rate of aluminum reduction. B) Cryolite-bauxite mixtures melt at lower temperatures than pure bauxite. C) Cryolite makes aluminum more corrosion resistant. D) Cryolite is reduced to aluminum at the cathode. E) Cryolite is oxidized to F₂(g)at the anode.

Question

Quizplus · Accepted Answer

Cryolite is used in the production of aluminum as a solvent for aluminum oxide, which is then electrolyzed to produce aluminum metal. The addition of cryolite reduces the melting point of the mixture, allowing for lower temperature electrolysis and lower energy consumption. Cryolite does not function as a catalyst, nor does it undergo reduction or oxidation in the process. It also does not affect the corrosion resistance of the resulting aluminum.
