JEE MainChemistryElectrochemistryMCQ+4 / −1
Which of the following statements is not correct about rusting of iron?
  1. A
    Rusting of iron is envisaged as setting up of electrochemical cell on the surface of iron object.
  2. B
    Dissolved acidic oxides SO2,NO2\mathrm{SO}_2, \mathrm{NO}_2SO2​,NO2​ in water act as catalyst in the process of rusting.
  3. C
    Coating of iron surface by tin prevents rusting, even if the tin coating is peeling off.
  4. D
    When pH\mathrm{pH}pH lies above 9 or 10, rusting of iron does not take place.
