Question

Aluminium is placed higher in the reactivity series. Thus, logically, it should corrose faster than iron. So, how can aluminium resist corrosion so much while iron can not?

Answer 1

Answer:

Aluminium reacts with air and forms a thin layer of aluminium oxide on it. This layer of oxide prevents further reactions and protects the metal from corrosion. If this oxide layer formation is more uniform, the metal below the layer would be well-protected.

Answer 2

Answer:

Aluminium reacts with air and forms a thin layer of aluminium oxide on it. This layer of oxide prevents further reactions and protects the metal from corrosion. If this oxide layer formation is more uniform, the metal below the layer would be well-protected.
