Although aluminium is higher than iron in the reactivity series,aluminium utensils do not corrode as easily as iron utensils.Explain
Aluminium forms a thin layer of oxide on its surface when exposed to air, which acts as a protective barrier that prevents further corrosion. This oxide layer is very stable and does not easily react with water or other substances in the environment, making aluminium utensils resistant to corrosion.
In contrast, iron is more reactive and readily reacts with oxygen and water to form iron oxide (rust), which is a less stable compound that continues to corrode and degrade the metal. This is why iron utensils are more prone to rust and corrosion compared to aluminium utensils.
Additionally, aluminium is also less likely to react with acidic or alkaline substances commonly found in food, further contributing to its resistance to corrosion in kitchen environments.
