Displacement Reactions
Displacement Reactions
Displacement Reactions
A more reactive metal (one that forms positive ions more easily) can remove a less reactive metal from a compound. This is called a displacement reaction.
Displacement order
Displacement order
- A metal can only displace another metal from a compound if it is located above it in the reactivity series.
Example of a displacement reaction
Example of a displacement reaction
- Calcium is higher in the reactivity series than copper. This means that calcium is able to displace copper from a copper sulfate solution to create calcium sulfate.
- Calcium + copper sulfate → calcium sulfate + copper
- Ca(s) + CuSO4(aq) → CaSO4(aq) + Cu(s)
- Platinum, on the other hand, is less reactive than copper and so would not be able to displace copper from a copper sulfate solution.
