* Activity Series: Copper is less reactive than iron. The reactivity series of metals helps us predict which metal will displace another from its salt solution. Copper is lower in the reactivity series than iron, meaning it cannot displace iron from its compound.
* No Redox Reaction: For a reaction to occur, there needs to be a transfer of electrons (a redox reaction). In this case, copper would need to lose electrons (oxidize) and iron would need to gain electrons (reduce). Since copper is less reactive, it is less likely to give up electrons to iron ions.
In summary:
* Copper will not displace iron from the solution.
* No visible changes will be observed.
* The solution will remain green (due to iron sulfate) and a piece of copper metal will be present.
