Oxidation Reactions

The video explains how metals react with oxygen, focusing on oxidation and corrosion. Aluminium forms a protective oxide layer that prevents further reaction, while iron rusts when exposed to water and oxygen, forming hydrated iron oxide. The video highlights both destructive and beneficial aspects of oxidation.
