    • Flame Test -
      • Calcium = brick red
      • Potassium = lilac
  • Copper = green/blue
    • Precipitation reactions
      • Ion Tests
        • Aluminium = white
        • Copper(II) = pale blue
      • Add a few drops of Sodium Hydroxide solution to the substance and the precipitate formed identifies the ion
        • Precipitation reactions
          • Aluminium = white
          • Copper(II) = pale blue
      • Calcium = white
        • Iron(II) = green
          • Iron(III) = brown (rust)
            • Halide ion test
              • Chloride = white
              • Iodide = yellow
            • add silver nitrate solutions and dilute nitric acid and it forms a silver halide precipitate
              • Halide ion test
                • Chloride = white
                • Iodide = yellow
            • Bromide - cream
              • Ammonium ions
                • warming substance with sodium hydroxide solution
