And just as Stan is a stronger bully
then Kyle, and is able to kick him out to be with Piggy, so it is with
iron and copper.
Because
iron (Fe) is a more reactive metal (it occurs higher up in the reactivity
series), it is able to displace copper ions from the solution and
take it’s place.
CuSO4 (aq) + Fe(s) ® FeSO4 (aq) + Cu(s)
Ionic equation: Cu2+ (aq) + Fe(s) ® Fe2+ (aq) + Cu(s)
