DISPLACEMENT REACTIONS

  • Instructions
  • Care! You should wear GOGGLES and LAB-COATS at all times during this practical
  • Obtain a dropping tile
  • Add a few drops of each of the solutions to individual ‘holes’ in the dropping tile. Make sure you know which solution is which
  • Choose a metal
  • Add one piece of that metal to each of the solutions
  • Observe – you will need to watch carefully for any evidence of a reaction taking place
  • If a reaction takes place, put a tick into the relevant box. If no reaction takes place, put a cross.
  • If a reaction takes place, try and describe what is happening
  • Wash all the reactions into a large beaker – do NOT put any solids into the sink!
  • Repeat for each metal using fresh solutions

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

slide24

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate 

slide25

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

slide26

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

slide27

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate 

slide28

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate  lead (II) sulphate + copper

slide29

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate  lead (II) sulphate + copper

lead is more reactive than copper

slide30

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate  lead (II) sulphate + copper

lead is more reactive than copper

but

copper + lead (II) sulphate 

slide31

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate  lead (II) sulphate + copper

lead is more reactive than copper

but

copper + lead (II) sulphate  no reaction

slide32

DISPLACEMENT REACTIONS

Summary

More reactive metals can displace less reactive metals from their solutions

e.g.

magnesium + iron (II) nitrate  magnesium nitrate + iron

magnesium is more reactive than iron

and

lead + copper (II) sulphate  lead (II) sulphate + copper

lead is more reactive than copper

but

copper + lead (II) sulphate  no reaction

copperis not more reactive than lead
