Question

Aluminium is above iron in the reactivity series. However, its reactions with oxygen and water seem to indicate that it is less reactive than iron. Explain​

Answer 1

Answer:

Explanation:

Because even though aluminum is more reactive than iron it does not corrode as much as iron. Aluminum reacts with oxygen in the air to form a layer of oxide which protects the aluminum from further oxidation. On the other hand the oxides of iron (rust) tend to fall away, exposing the unreacted iron to further oxidation.

Answer 2

Explanation:

However, its reaction with oxygen and water seem to indicate that it is less reactive than iron. It appears so, because Aluminum reacts with the oxygen in the air to form Aluminium Oxide, which further acts as a protective layer over the pure Aluminium. ...
