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…

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
