[6 marks]

• What reactants?

  To form a salt (like Copper Chloride), react:

  Metal carbonate/ Metal oxide/ Metal hydroxide

  • Use Copper Carbonate

  with Acid

  • Use Hydrochloric Acid

• How will you prepare and mix them?

  • Warm the acid

  • Add Copper Carbonate powder in excess

  • Stir

  • Stop adding when fizzing stops

• How will you get rid of the excess powder?

  Filter it

• How will you make the Copper Chloride liquid into crystals?

  • Heat it in an evaporating dish above a hot water bath
