WebThe corrosion of iron is an electrochemical process. The anode region and cathode region are present in iron. Iron(II) is oxidized to Iron(III) by oxygen and is then converted to rust. … WebMany metals become corroded by exposure to the air. The corrosion of iron and steel is called rusting. The most common example of corrosion is that corrosion comes off from the metal surface, rusting of iron causing iron to change into rust – an orange – red powdery a fresh metal surface is exposed and the process of corrosion continues.
