Aluminium chloride exists as a dimer, `Al_2Cl_6` in solid state as well as in solution of non-polar solvents such as benzene. When dissolved in water, it gives:
A
`Al^(3+) + 3Cl^(ѳ)`
B
`Al_2O_3 +6HCl`
C
`[Al(H_2O)_6]^(3+) + 3Cl^(ѳ)`
D
`[Al(OH)_6]^(3-) + 3HCl`
Text Solution
Verified by Experts
The correct Answer is:
C
The dimeric form `Al_2Cl_6` is retained in non-polar solvent but is broken into `[Al(H_2O)_6]Cl_3` on dissolution in water due to high heat of hydration.
