Experiments in which I react copper (II) sulfate with iron.
CuSO4 + Fe → FeSO4 + Cu
It is a redox and simple displacement reaction. Copper is reduced to metallic copper and metallic iron is oxidized to form part of iron (II) sulfate.
I also carry out a similar reaction, but with zinc from the galvanized wire. Zinc is more reactive than iron and we can see how the reaction occurs more quickly.
CuSO4 + Zn → ZnSO4 + Cu
If I try to make the copper react with the iron (II) sulfate, no reaction occurs. This is because copper is less reactive than iron. I present the activity series of metals or reactivity series of metals. It shows the metals classified from most reactive to least reactive. For example, potassium (K) is very high because it is very reactive, while platinum (Pt) is very low because it is very unreactive.
