Correct answer: (b) a mixture of Al2O3 and carbon in dry Cl2 gas
Explanation:
Al2O3 can be converted to anhydrous AlCl3 by heating a mixture of Al2O3 and carbon in dry Cl2
Al2O3 + 3C + 3Cl2 \(\overset{1000°C}\longrightarrow\) 2AlCl3 + 3CO
2AlCl3 → vapours + cooled → Solid anhydrous aluminium chloride
