What change occurs in heating aluminum foil? is it

Sep 14, 2007· Likely, aluminum foil (used to cover roasting turkeys, etc.) would no include chemicals that could out gas (into the turkey). Therefore heating pure aluminum should not cause a chemical change. Because pure aluminum melts at about 1220F, high heat could cause a change of state (solid to melt) and the foil would soften (physical change) on the way to a higher temperature.

Chemical Reaction of aluminum foil in CuCl2 solution

Aluminum is more reactive than copper. Therefore when aluminum foil is put into the copper salt solution, aluminum atoms on the surface of the foil (in contact with the solution) reacts and takes the place of copper(II) ions in the solution (it now becomes aluminum chloride solution). That is why the blue solution becomes colorless.
