Question

Aluminum is a very recative metal. However, the foods in aluminium pots don't react with the pots? Give reason. ​

Answer 1

Answer:

Because a layer of Aluminium oxide is formed over the surface which prevents aluminium to react with food

Answer 2

Aluminium is a very reactive metal but the food in aluminum pots doesn't react with the pot because-

• The surface of aluminium is coated with a thin protecting layer of chemical compound (oxide) at standard temperature that prevents the metal from further corrosion. Thus, food  do not attack aluminium and food can be safely braised in such vessels.
• Because a layer of Aluminium oxide is coated over the surface which prevents aluminium to react with food.
