Open in App
Solution

Corrosion:

  • Corrosion is a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air.
  • Corrosion makes the metal surface dull. Color change on the surface is also seen evidently due to corrosion.
  • Copper (Cu) is a metal that naturally turns green over time on oxidation.
  • Therefore, the metal which turns green when oxidized is Copper.
  • The reaction involved in this process is :

Cu(s)+H2O(l)+O2(g)+CO2(g)CuCO3(s).Cu(OH)2(s)(Greenincolour)
