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:
$Al^{3+} +3Cl^-$
$[Al(H_2 O)_6 ]^{3+} + 3Cl^-$
$[Al(OH)_6]^{3-} + 3HCl$
$Al_2O_3 + 6HCl$
Aluminium is obtained by
Assertion : Coloured cations can be identified by borax bead test.
Reason : Transparent bead $(NaBO_2 + B_2O_3)$ forms coloured bead with coloured cation.

$I.$ $Al_2Cl_6$ $II.$ $B_2H_6$
$III.$ $Fe_2Cl_6$ $IV.$ $Si_2H_6$
Maximum number of atoms which are present in one plane of $H_3BO_3$?
