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..

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 ..

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 coatin..

1) Water on the metal surface dissolves CO 2 and O 2 from the air. fig 5.16 - Corrosion of iron 2) Fe in contact with dissolved CO 2 and O 2 undergoes oxidation. 3) Electrons lost by Fe are taken by H +..

Physical Properties - Pure iron is a grey white metals. It appears to be brown due to rusting. It is malleable, ductile and magnetic. A good conductor of heat and electricity. Iron has a high density and high melting poi..

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..

Iron, which has to be continuously remain in contact with water, as in the body of ships, can be given a kind of electronic protection. Pieces of a more reactive metal, such as magnesium are attached to that part of the ship that remains under water. When in contact with water, the magne..
