The process ofcorrosion ofiron is known as rusting. Rust appears to be a hydrated ferricoxide Fe_2O_3, xH_2O, Both O_2 & H_2O are required for rusting. Iron can be protected from the rusting by use of following compounds. i) Applying paints, lacquers and enamells on the surface ofiron ii) By forming a firm and coherent protective coating of ferroroferric oxide. This is done by passing steam over hot iron iii) By coating a thin film of Zinc, Tin, Nickel, chromium, aluminium etc, on the surface of iron If plated with Zinc, the reaction of products of Zinc with O_2 and H_2O form a coating which sticks to the surface and there by protects iron Zinc protects iron from corrosion because
