Why is a layer of zinc coated over iron?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding Corrosion**: Corrosion is a natural process that occurs when metals react with moisture and oxygen in the environment. Iron, in particular, is prone to rusting when exposed to these elements. **Hint**: Think about how metals react with water and air. What happens to iron when it is exposed to moisture? 2. **Introduction to Galvanization**: To protect iron from corrosion, a process called galvanization is used. This involves applying a protective layer of zinc over the iron surface. ...
