Corrosion is an elctrochenmical process . It involves

Answer»

Loss of electrons by Iron, `FE rarr Fe^(+2) + 2e^(-)` . Ie, Iron ACTS as an anode
Inpurities act as a cathode. ELEMENTS are used in forming hydroxyl ions `H_2O + O+2e^(-) rarr 2OH^(-)`
FERROUS ions are osidised to ferric ions in presence of dissolved oxygen
`2Fe^(+2) + O + H_2O rarr 2Fe^(+3) + 2HO^-`
All the above reactions

Solution :CORROSION is electrochemical oxidation of iron
