Question

can anyone help me with the above question?

Answer 1

The solution of CuSO4 , ionization takes place due to which ions of Cu+2 and SO4-2 are formed , in the electronegative series of metals Cu is more reactive in comparison to Fe. This enables Cu to displace Fe ; the same can be summarized as under : Fe + CuSO4 = Fe SO4 + Cu , 

2 Fe + 3 CuSO4 = Fe2 ( SO4 )3 , 

Thus Cu ions f the CuSO4 solution attacks the iron pot and Fe is getting chemically corroded as Ferrous or Ferric Sulphate

Answer 2

Fe+CuSO4=FeSO4+ Cu

Iron displaces Copper from Copper sulphate solution and forms iron sulphate.
