Corrosion of iron occurs by rusting. Rust is a form of a hydrated oxide(s) of iron formed as a result of chemical reactions of iron with the atmosphere. This ‘atmospheric rust formation’ is a slow process. Iron is a chemically ‘active’ element and possesses the tendency to react with other reagents spontaneously. Artificially ‘rusting’ may be induced readily by the use of suitable chemicals and little energy input. Such reactions and methods help us to study the rusting process in a vivid manner. This technique relies on the main usage of acids and electricity. Experiments were carried out to study the ionization of iron and its subsequent oxidation into higher oxidation states with suitable conditions and have been elaborated in this paper.
