$A{l}_2{O}_3$ can be converted to anhydrous $AlC{l}_3$ by heating.

• A. A mixture of and carbon in dry gas
• B. with gas
• C. with Hcl gas
• D. with Nacl I solid state

Answer 1

The correct option is A

A mixture of and carbon in dry gas

$A{l}_2{O}_3$ can be converted to anhydrous $AlC{l}_3$ by heating a mixture of $A{l}_2{O}_3$and carbon in dry $C{l}_2$ gas

$A{l}_2{O}_3+3C+3C{l}_2\to 2AlC{l}_3+3CO$
