Heating of an aqueous solution of aluminium chloride to dryness will give
A
`Al(OH)Cl_2`
B
`Al_2O_3`
C
`Al_2Cl_6`
D
`AlCl_3`
Text Solution
Verified by Experts
The correct Answer is:
B
Aqueous solution of `AICI_3` is acidic due to hydrolysis. `AlCl_3 + 3H_2O hArr Al(OH)_3 + 3HCl` On strongly heating `Al(OH)_3` is converted into `Al_2O_3`. `2Al (OH)_3 overset(Delta)to Al_2O_3 + 3H_2O`
