Film summary

Why do we cook our food wrapped in aluminum foil? Why does metal rust? It all comes down to oxidation reactions. Discover what happens to cause these reactions and how to stop them.

Key facts

  • The combustion of any element is always an oxidation reaction.
  • Oxidation can be both destructive and useful.
  • Rusting of iron attacks structures such as bridges and boats.
  • Aluminum oxide provides a protective layer on the foil and prevents oxygen and water reaching the pure metal.

Transcript

This is the reaction of pure aluminum powder when heated in air.

It almost explodes, giving out a lot of heat and forming aluminum oxide.

Aluminum + oxygen → aluminum oxide
4Al(s) + 3O2(g) → 2Al2O3(s).

Combustion of any element is always an oxidation reaction... so this is one way that a metal …
