Vedclass · Answer

(A) Step $1$: Aluminium chloride $(Al_2Cl_6)$ is a covalent dimer in non-polar solvents.Step $2$: When it dissolves in water, it undergoes hydration to form the stable octahedral complex ion, $[Al(H_2O)_6]^{3+}$, and releases chloride ions.Step $3$: The balanced chemical reaction is: $Al_2Cl_6 + 12H_2O \rightarrow 2[Al(H_2O)_6]^{3+} + 6Cl^-$.Step $4$: Therefore, the species formed in the aqueous solution are $[Al(H_2O)_6]^{3+}$ and $Cl^-$ ions. Option $A$ represents the correct stoichiometry for one mole of $AlCl_3$ equivalent.

Aluminium chloride exists as a dimer, $Al_2Cl_6$, in the solid state as well as in solutions of non-polar solvents such as benzene. When dissolved in water, it gives:
