Question

$Al_2O_3$ can be converted into anhydrous $AlCl_3$ by heating

• A. $Al_2O_3$ with HCI gas
• B. $Al_2O_3$ with NaCI in solid state
• C. $Al_2O_3$ a mixture of $Al_2O_3$ and carbon in dry $Cl_2$ gas
• D. $Al_2O_3$ with $Cl_2$ gas

Answer 1

Answer: (C)

$Al_2O_3$ a mixture of $Al_2O_3$ and carbon in dry $Cl_2$ gas

Answer 2

$Al_2O_3$ may be converted into anhyd. $AlCl_3$ by heating a mixture of $Al_2O_3$ and carbon in dry chlorine.

$Al_2O_3 + 3C + 3Cl_2 \longrightarrow Al_2Cl_6$ $22\,mm$ Hot and dry $8\,mm$ Anhy $AlCl_2$
