Question
What element is used to coat galvanized
iron?Solution
Galvanization involves coating iron or steel with zinc to prevent rusting. The process involves dipping the base metal into molten zinc, forming a protective barrier that not only shields the iron from moisture and oxygen but also provides sacrificial protection—the zinc corrodes first, thereby offering extended protection to the underlying metal.
