why reactivity of aluminum decreases when dip in nitric acid

Answers

Answered by priyanshiojha51

When aluminium is dipped in nitric acid a layer of aluminium oxide is formed on the metal. This happens because nitric acid is a strong oxidizing agent. The layer of aluminium oxide prevents further reaction of aluminium. Due to this, the reactivity of aluminium decreases.
