$Al_2O_3$

Vedclass · Answer

(C) An aqueous solution of $AlCl_3$ undergoes hydrolysis to form $Al(OH)_3$ and $HCl$ as follows:$AlCl_3 + 3H_2O \rightarrow Al(OH)_3 + 3HCl$Upon heating the solution to dryness,the volatile $HCl$ gas escapes.The remaining $Al(OH)_3$ is thermally unstable and decomposes to form aluminium oxide $(Al_2O_3)$ and water vapor:$2Al(OH)_3 \rightarrow Al_2O_3 + 3H_2O$Therefore,the final product obtained is $Al_2O_3$.

Heating an aqueous solution of aluminium chloride to dryness will give
