What is the process of coating iron with zinc to prevent rusting called?

Answer and explanation

Correct answer: Galvanization

The process of applying a protective zinc coating to iron or steel is called galvanization. Zinc prevents iron from coming into contact with air and moisture; even if the coating is scratched, zinc oxidises preferentially and protects the iron. Electroplating is a general method for depositing metals, whereas the specific zinc coating on iron is called galvanization. Exam tip: zinc-coated iron is known as galvanised iron.
