Which metal is primarily used to coat iron sheets in the process of galvanization to prevent atmospheric corrosion?

💡 Solution & Explanation

Galvanization involves coating iron or steel sheets with a thin layer of zinc to shield them from rust through preferential oxidation. Metals like copper and tin fail to provide the same sacrificial anodic protection because zinc possesses a higher reduction potential than iron. This industrial chemistry process is widely applied in manufacturing corrosion-resistant building materials.
