    AlCl3, have a vague memory of doing this recently...thinking maybe Friedal Crafts? Cl+ ions formed? Not sure...if I work something out I'll get back to you!

    EDIT: I think I'm totally wrong with the above because (worryingly!) I don't have the foggiest idea what a lewis acid is! Must start revising soon....this is really not good!! Sorry I can't help at the moment, but I will look into it!

    A lewis acid will accept a lone pair of electrons. Aluminium is electron deficient in the trichloride, and will (I hope) form the species AlCl4(-) in HCl, acting as a lewis acid and forming a coordinate bond with the chloride.
