Iron is often galvanized in order to
Answer Details
Iron is often galvanized in order to protect it against corrosion. Galvanizing is a process of coating a layer of zinc on the surface of iron or steel to prevent the formation of rust. Zinc is more reactive than iron and when it is exposed to air and water, it forms a layer of zinc oxide which acts as a protective layer for the underlying iron. This prevents the iron from rusting and increases its lifespan. Galvanizing is commonly used in outdoor applications where the iron or steel is exposed to the elements and is susceptible to corrosion.
