The chemistry of corrosion of iron is essentially an electrochemical phenomenon. Explain the reactions occurring during the corrosion of iron in the atmosphere.

Answer»

Solution :
REACTIONS occuring during the corrosion:
`{:("Oxidation", Fe(s) to Fe^(2+)(AQ) + 2e^(-)),("Reduction", O_(2)(g) + 4H^(+) (aq) + 4e^(-) to 2H_(2)O(l)):}`
Atmospheric oxidation: `2Fe^(2+)(aq) + 2H_(2)O (l) + 1/2O_(2)(g) to Fe_(2)O_(3) (s) + 4H^(+)(aq)`
