Question

A solution of CuSO4 was kept in an iron pot. After few days the iron pot was found to have a number of holes in it. The balance equation of the reaction involve is:
  1. 2Fe+CuSO4Fe2(SO4)3+Cu
  2. Fe+CuSO4FeSO4+Cu
  3. Fe+CuSO4Fe2SO4+Cu
  4. 3Fe+CuSO4Fe3(SO4)4+Cu

A
2Fe+CuSO4Fe2(SO4)3+Cu
B
Fe+CuSO4FeSO4+Cu
C
3Fe+CuSO4Fe3(SO4)4+Cu
D
Fe+CuSO4Fe2SO4+Cu
Solution
Verified by Toppr

Iron(Fe) being more reactive than copper(Cu) displaces latter from CuSO4 to form FeSO4. The reaction can be written as:
Fe+CuSO4FeSO4+Cu
