Question

the most durable metal plating on iron to protect against corrosion is

​copper plating

tinplating

zincplating

nickelplating

leadplating

Answer 1

zinc plating is best metal plating in iron to protect against corrosion because zinc is more reactive than iron hence it react with the moisture and oxides present in the surrounding thus it react with atmospheric oxides and moisture and thus prevent from rusting the process of zinc coating on iron to prevent from rusting is called galvanization
