Out of `Sn` and `Zn` which one protects `Fe` better even after cracks ?

Text Solution

AI Generated Solution

To determine which metal, tin (Sn) or zinc (Zn), protects iron (Fe) better even after cracks, we need to analyze their electrochemical properties, specifically their reduction potentials. ### Step-by-Step Solution: 1. **Understanding Corrosion**: - Iron is prone to corrosion, commonly referred to as rusting, where it gets oxidized to Fe³⁺ ions in the presence of moisture and oxygen. 2. **Sacrificial Protection**: ...
