1. Lesson Starter: place in order from most to least reactive
Potassium
Gold
Hydrogen
Lead
Zinc
Silver
Lithium
Aluminium

2. To be able to explain what happens during a displacement reaction
Learning Intention
To be able to explain what happens during a displacement reaction

3. Reactivity series
The reactivity series acts as a ‘league table’ showing which metals are more reactive and therefore will displace another in a reaction.

4. Displacement
During a displacement reaction the metal in a compound is replaced with a more reactive metal to form a new compound.
Zinc
Copper
Sulfate

5. Model 1
Like people compounds find some partners more attractive than others, and will ‘ditch’ one metal for another.

6. Worked examples Magnesium metal + Copper Sulphate solution-
Lithium metal + Sodium Chloride solution-
Zinc metal + Lithium Sulphate solution-

7. Over to you..
PREDICT of a displacement reaction will occur and get them checked
Try out a few of the reactions
Half fill the test tube with the solution stated and then add the metal stated.
Note any observations in your jotter

8. Written Examples Magnesium + Potassium Sulphate-
Lithium + Iron Nitrate-
Lithium + Aluminium Sulphate-
