Question

Aqueous solution of $\mathrm{AlCl}_{3}$ is acidic as it gives $\mathrm{HCL}$ on hydrolysis.

$\mathrm{AlCl}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarro

Vedclass · Accepted Answer

$Al_2O_3$

Vedclass · Answer

Aqueous solution of $\mathrm{AlCl}_{3}$ is acidic as it gives $\mathrm{HCL}$ on hydrolysis.

$\mathrm{AlCl}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Al}(\mathrm{OH})_{3}+\mathrm{HCl}$

On strongly heating $\mathrm{Al}(\mathrm{OH})_{3}$ is converted into $\mathrm{Al}_{2} \mathrm{O}_{3}$

$\mathrm{Al}(\mathrm{OH})_{3} \rightarrow \mathrm{Al}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2} \mathrm{O}$

$\mathrm{AlCl}_{3}$ on heating gives $\mathrm{Al}_{2} \mathrm{O}_{3}$

Heating an aqueous solution of aluminium chloride to dryness will give:
