  • When CuSO4 / H2SO4 mixture is added , H2SO4 being an oxidizing acid oxidizes the surface layer of Al foil to Al2O3 , while HCl is not an oxidizing acid. Hence Surface layer was available to react for the displacement reaction.Also CuCl2 , is more volatile salt to show its greenish blue magic in the flame test.
