Vedclass · Answer

Aqueous solution of $AlCl _3$ is acidic as it gives $HCL$ on hydrolysis.

$AlCl _3+3 H _2 O \rightarrow Al ( OH )_3+ HCl$

On strongly heating $Al ( OH )_3$ is converted into $Al _2 O _3$.

$Al ( OH )_3 \rightarrow Al _2 O _3+3 H _2 O$

$AlCl _3$ on heating gives $Al _2 O _3$.

Heating an aqueous solution of aluminium chloride to dryness will give
