Metal Displacement Reactions

2P9: Wednesday 17th November

Quick review…

• Today you will be doing the Metal Displacement Experiment:– Aim: The aim of this experiment is to see what happens when

a metal is added to a metal salt

• What does Displacement mean?– To remove or kick something out!

• When a displacement reaction occurs we see a chemical reaction taking place– Name three things we might see happening…

Word equations

• Magnesium + Zinc sulphate Magnesium sulphate + Zinc

• Zinc + Sodium sulphate no reaction

• Sodium + Zinc sulphate Sodium sulphate + Zinc

• Copper + Silver nitrate Copper nitrate + Silver

• Aluminium + Copper bromide Aluminium bromide + Copper

• Gold + Silver nitrate no reaction

Reactivity Series

• Potassium• Sodium• Calcium• Magnesium• Zinc• Copper• Silver

Most reactive

Least reactive

Conclusion

• A displacement reaction will only work if the metal you add into the reaction is HIGHER in the reactivity series than the metal that is in solution
