प्रश्न
Aluminium is a more active metal than iron, but suffers less corrosion. Why?
उत्तर
Aluminium is a more active metal than iron, but suffers less corrosion because of the formation of a thin, transparent, protective, non-porous adhering film of aluminium oxide on the surface of aluminium which makes it resistant to corrosion .
