Rusting / Oxidation of iron is exhibited :

Explanation:

i)  When Fe is converted to Fe_2O_3.xH_2O , it is called rusting of iron. Rust is basically iron oxide which is reddish-brown in color . This iron oxide is formed by the reaction of iron and oxygen in presence of water or air or moisture. Rust is made up of hydrated iron(III) oxides . The property exhibited here can also be oxidation of iron.

ii)  Conversion of Fe to FeCl_2 or FeCl_3 is also an oxidation process.  Metallic iron when reacts with dil HCl produces only ferrous chloride. Heating iron with chlorine gas results in the formation of ferric chloride , FeCl_3.  This also is oxidation , where Cl_2 acts as an oxidant and oxidation of Fe^2^+ to Fe^3^+ takes place.

  • FeCl_2 is quite sensitive to air. A solution of FeCl_2 when exposed to air turns cloudy , again because of oxidation of Fe(2+) and results in the formation of basic Fe(3+) compounds.
