Who has not seen the damaging effects of rusting of iron! During the process of rusting the oxide that forms is brittle and chips off from the surface. This exposes yet another layer below to the deleterious effects of moisture and air. Thus, rusting destroys the..

Protective coating - Rusting can be prevented, by applying a protective coating on the surface of the iron, so that the iron does not come in contact with air and moisture simultaneously. This coating can be of two types: (i) Non-metallic coating (ii) Metallic coati..

Conditions for Rusting of Iron - The presence of water and oxygen is essential for the rusting of iron. Impurities in the iron, the presence of water vapor, acids, salts and carbon dioxide hastens rusting. Pure iron does not rust in dry and carbon dioxide fre..

Iron (or steel) corrodes more quickly than most other transition metals and readily does so in the presence of both oxygen (in air) and water to form an iron oxide. Rusting is speeded up in the presence of salt solution. Rusting is Fe (s) + O 2(g) + H 2 O (I) Fe 2 O 3 . x..

The nails placed in the water, as well as the ones suspended in the air rust. The water contains dissolved air, and the air contains water vapor...

The alloys of iron have a strong resistance to rusting. Iron can be converted to stainless steel by fusing it with carbon, chromium and nickel in a definite proportio..

Corrosion - The process of slowly eating away of the metal due to attack of the atmospheric gases on the surface of metals; forming oxides, carbonates, sulphides is called corrosion (e.g., tarnishing of Ag, development of a green coating on Cu and bronze etc.) Corrosion of iron is called rusti..
