Question

Aluminium protects itself against corrosion. Discuss why it is necessary to anodize aluminium
to make it corrosion resistant.
​

Answer 1

Answer:

Aluminium protects itself against corrosion upon exposure to air by forming a layer of aluminium oxide. If this layer is made more uniform, it protects the aluminium underneath more effectively. Thus, this is done by a process called anodizing to make it corrosion resistant.
