Vedclass · Answer

(A) Aluminium chloride $(Al_2Cl_6)$ is a covalent dimer in non-polar solvents. When it dissolves in water,it undergoes hydration to form the stable octahedral complex ion,$[Al(H_2O)_6]^{3+}$,and releases chloride ions. The reaction is: $Al_2Cl_6 + 12H_2O \rightarrow 2[Al(H_2O)_6]^{3+} + 6Cl^-$. Therefore,the correct species formed are $[Al(H_2O)_6]^{3+}$ and $Cl^-$ ions.

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:
