Question

As compared to iron, aluminum has :

• A. higher tendency to oxidize
• B. less tendency to oxidize
• C. equal tendency to oxidize
• D. none of above

Answer 1

The correct option is A higher tendency to oxidize

As compared to iron, aluminum has less tendency to oxidize.

Aluminium is indeed a more reactive element than iron. However aluminium in sheet form reacts with atmospheric oxygen forming a layer of aluminium oxide on its surface. The oxide layer is very tightly bound on the surface of aluminium; and the oxide itself is not very reactive.
