This document discusses a metal displacement experiment where different metals are added to metal salt solutions. The goal is to see if a displacement reaction occurs where the added metal replaces the metal in the salt solution. Results are recorded and word equations are written for reactions that took place. A reactivity series is also presented that lists metals from most reactive to least reactive, and it is concluded that a displacement will only occur if the added metal is higher in the reactivity series than the metal already in solution.

2. 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…

5. 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

6. Reactivity Series
• Potassium
• Sodium
• Calcium
• Magnesium
• Zinc
• Copper
• Silver
Most reactive
Least reactive

7. 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
