Is Aluminum Foil A Mixture?

Yes, aluminum foil is a mixture.
A mixture is a material that is made up of more than one substance. These substances are not chemically bonded to each other. They can be separated without the need for a chemical reaction.
Aluminum foil is mostly aluminum, but not quite. It contains trace elements of metals and other minerals, depending on where the aluminum ore was originally mined. The refining and smelting process does not quite remove all of the traces, leaving them in the aluminum foil at a molecular level.
Since these substances are not chemically bonded to the aluminum foil, the resulting substance is a mixture.
Theoretically, aluminum foil could not be a mixture, if the aluminum ore used to make the aluminum-foil-a-pure-substance">foil was sufficiently refined to remove impurities.
But since that rarely happens, the aluminum foil is a mixture.
