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 , `AlCl_(3) (aq)` gives `Al_(2)O_(3)`
`2AlCl_(3) + 6 H_(2)O rarr 2Al(OH)_(3) + 6HCl`
`2Al(OH)_(3) overset("Dryness")rarr Al_(2)O_(3)+ 3H_(2)O`
