Introduction to corrosion and the conditions required for rusting.
To understand why iron rusts, scientists use a simple 3-bottle experiment with iron nails:
This proves that both moist air and water are essential for rusting.
Explain burning of magnesium and the basic nature of metal oxides.
When you ignite a magnesium ribbon in the air, it burns rapidly with a dazzling white flame. The ribbon transforms entirely into a fine, white powder. This new substance is magnesium oxide, formed because the magnesium reacted with oxygen in the air.
