In the reaction Fe + Cu2+ \(\to\) Fe2+ + Cu,iron displaces copper ions to from copper. This is due to the fact that
irn is in the metallic from while the copper is in the ionic from
the atomic weight of copper is greater than that of iron
copper is greater than iron
copper metal has more electrons than iron metal
iron is higher in the electrochemical series than copper
