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

A

`AlCl_3`

B

`Al_2Cl_6`

C

`Al_2O_3`

D

`Al(OH)Cl_2`

Text Solution

Verified by Experts

The correct Answer is:
C

On heating `AlCl_3`(aq) to dryness, `Al_2O_3` is formed.
`2AlCl_3 +6H_2O rarr 2Al(OH)_3 +6HCl`
`Al(OH)_3 rarr Al_2O_3 +3H_2O`
