Sometimes when foods are stored in aluminum foil, or when foil is used to cover a pan of food, the foil will develop holes and look like it is being eaten away. Two things may be the cause. 1) When aluminum and a dissimilar metal are in contact in the presence of moisture, an electrolytic reaction may occur causing a breakdown of the aluminum. To prevent this reaction, use plastic wrap to cover metal containers (silver, stainless steel, or iron used to store food. 2) If the aluminum foil was not used with a dissimilar metal container, the reaction was probably a chemical one. It is possible for heavy concentrations of salt, vinegar or some other acidic compound, or highly spiced foods to cause the foil to disintegrate. The product of either of these reactions is an aluminum salt. It does not harm the food but you will want to scrape any deposit off the food as it may impart an undesired flavor and color.

Aluminium foil disintegrates in a convection oven because the heat rays of the oven hits the aluminium foil but gets reflected by the foil. Thus, the oven over heats and the aluminium foil disintegrates.
The acid erodes the aluminum foil, Try this: Cut one tomato in half, place it in auminum foil, place in fridge, eventually, you will see specks of metal ( the aluminum) :D
Aluminum is element. Aluminum foil is made entirely of aluminum.
Aluminum foil is made of Aluminum, which is an element. So yes Aluminum foil is a element
Tin foil... tin Aluminum foil... aluminum :)
Because all aluminum foil is not equal. Aluminum foil is available in a variety of thicknesses.
Only a single component makes up aluminum foil, which is the aluminum element. Hence, aluminum foil is considered as a pure substance.
it is an element
