Question

To protect iron from rusting, it is coated with a thin layer of zinc. Name this process

Answer 1

• Iron forms rust or hydrated Iron oxide$({\mathrm{Fe}}_2{\mathrm{O}}_3.{\mathrm{xH}}_2\mathrm{O})$ by the reaction of oxygen and moisture present in the air.
• So, to prevent iron$\left(\mathrm{Fe}\right)$ from rusting, zinc$\left(\mathrm{Zn}\right)$ is mainly used for coating iron surfaces.
• The process of protecting iron surfaces from rusting by coating them with zinc metal is called galvanization.

Hence, the process is called galvanization.
