Aluminium chloride can form a dimer like 2 6 Al Cl . In solid-state as well as in the solution of non-polar solvents such as benzene aluminum chloride exists as a dimer. When it dissolves in water, it gives aluminium hexa hydroxide anion with hydrochloric acid, as follows. 3 2 6 2 2 6 Al Cl 12H O 2 A ] l H O 6 [ ( ) Cl + - + ® +
