Heating an aqueous solution of aluminium chloride to dryness will give

A

`AlCl_(3)`

B

`Al_(2)Cl_(6)`

C

`Al_(2)O_(3)`

D

`Al(OH)Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
On heating, it undergoes hydrolysis to give aluminium hydroxide which is dehydrated to give alumina.
`[Al(H_(2)O)_(6)]Cl_(6) overset(Delta)rarr Al(OH)_(3) + 3H_(2)O`
`2Al(OH)_(3) overset(Delta)rarr Al_(2)O_(3) + 3H_(2)O`
