Presentation Transcript
preparing sodium chloride
Preparing sodium chloride
  • Add NaOH to HCl slowly to get a neutral solution. (How?)
  • Concentrate the solution by evaporation until some white crystals around the edge of solution are seen.
  • Leave the solution to evaporate slowly at room temperature to get bigger crystals.
  • Separate the crystals by filtration.

Preparing salt from an acid and a base, CuSO4.5H2O
  • Add black copper oxide to sulphuric acid and stir with a glass rod.
  • Keep adding until no more will dissolve (react).
  • Filter the mixture in another beaker.
  • Pour the solution into an evaporating dish.
  • Stop heating when some crystals are seen around the edge of solution.
  • Leave the solution to crystallize slowly.
making insoluble salts
Making insoluble salts
  • Some salts are insoluble.
  • They can be prepared by a precipitation reaction.
other methods for soluble salts
Other methods for soluble salts
  • Acid + carbonate  salt + water + carbon dioxide
other methods for soluble salts8
Other methods for soluble salts
  • Acid + metal  salt + hydrogen

  • Decide a ‘salt’ for your group.
  • Design an experiment to prepare it.
  • In a piece of paper, write down the chemicals and apparatus required; draft the experimental procedure and hand it to your teacher for comment.

  • After making modification (if needed) to your designed experiment. Carry out the preparation in the laboratory periods.
  • Write a report on the designed experiment.
