Preparing Insoluable Salts

Method

  • Measure out 10cm3 of sliver nitrate solution and pour into a beaker using a measuring cylinder
    • After using the measuring cylinder rinse it out for next use
  • Measure out 15cm3 of sodium chloride solution into the mixture, stir using a glass rod
    • Reaction taking place should be:
      • Sliver Nitrate + Sodium Chloride -> Sodium Nitrate + Sliver Chloride (insoluble)
  • Place filter funnel at the mouth of the conical flask
  • Fold a piece of filter paper and place it into the filter funnel
    • Add a few drops of water to the funnel so the paper stays in place
  • Run the mixture through the filter
  • Rinse the beaker with distilled water and pour the washing through the funnel
  • After the filtrate has drained through the filter paper, add a little distilled water to wash the precipitate
  • Allow water to drain from the paper
  • Carefully open out the filter paper and place it by a warm, dark place to dry
