Iron is more electropositive than Silver as evident from their positions in the electrochemical series.Less electropoitve Silver ions #(Ag^+)# get reduced by the Iron #Fe# atom and as a result metallic silver is deposited on Iron electrode when dipped in silver ion solution. But Ag electrode does not interact with #Fe^"+3"# ions in solution.

#2Ag^+ +Fe->Fe^"+2"+2Ag#
