  • Where is metal extracted?
    From ores
  • What are some examples of ores?
    Haematite and bauxite
  • What can be extracted from Haematite?
    Iron
  • What can be extracted from bauxite?
    Aluminium
  • What does the method used for extraction depend on?
    Reactivity
  • What extraction is used for very reactive metals?
    Electrolysis
  • What extraction method is used for less reactive metals?
    Reduction with carbon
  • When is electrolysis used for extraction?
    When a metal is more reactive than carbon
  • When are other methods used to extract metals?
    When a metal is less reactive than carbon
  • What will a more reactive metal do in displacement reactions?
    It will displace a less reactive metal from a compound
  • What is an example of a displacement reaction?
    Aluminium+iron oxide > iron+ aluminium oxide
  • In a displacement reaction, what happens to iron oxide and aluminium?
    Iron oxide is reduced and aluminium is oxidised
  • What does a bigger difference in reactivity cause?
    More energy to be released
  • What will a more reactive metal do in solution?
    Displace a less reactive metal from a solution
  • What is an example of a displacement reaction in solution?
    Magnesium+copper sulfate > copper+magnesium sulfate
  • What type of reaction is this?
    Displacement reaction
  • What does the speed of which hydrogen bubbles are produced show us?
    How reactive a metal is
  • The quicker the fizzing the more reactive the metal is
  • Why are carbon and hydrogen included in the reactivity series?
    As they’re used to extract metals
  • What is the order of the reactivity series, top to bottom?
    Potassium, Sodium, Lithium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Hydrogen, Copper, Silver and Gold
  • Does reactivity increases as you go up the reactivity series?
    Yes.
