  • Qualitative Analysis
    • Quantitative versus Qualitative
      • Qualitative is IF
      • Quantitative is HOW MUCH
    • Used in science
      • Purity of drinking water
        • Why
          • Hard water does not form a lather
            • Impacts industrial processes and domestic activities
          • Acidic water could cause gastrointestinal related illnesses if drunk
          • Halogens in water could interfere with chemical reactions in industries
        • How much and how dangerous is monitered
      • Testing blood
        • Check for mineral deficiencies
    • Tests
      • Must be unique in order to identify SPECIFIC ions
      • Examples
        • Flame tests
          • Calcium (brick red)
          • Copper (blue green)
          • Sodium (yellow)
          • Potassium (lilac)
          • Ni-chrome wire is dipped into HCL and burned until it is clean
            • The unknown compond is made into a paste using HCL
              • Ni-chrome wire is dipped into the paste and then held over flame
                • Colour of flame used to identify ion
                  • Copper (blue green)
                  • Calcium (brick red)
                  • Potassium (lilac)
                  • Sodium (yellow)
        • Precipitation Tests
          • Metal ions
            • Sodium hydroxide solution added to sample
              • Forms a coloured precipitate
                • Copper(II)
                • Iron(III)
                • Calcium
                • Aluminium
                • Iron(II)
            • Copper(II)
            • Iron(II)
            • Iron(III)
            • Aluminium
            • Calcium
          • Halide ions
            • Dilute nitric acid and silver nitrate solution added to sample
              • Coloured precipitates form if this ion is present
                • Iodide
                • Bromide
                • Chloride
            • Chloride
            • Bromide
            • Iodide
        • Testing for ammonium ions
          • Sodium hydroxide solution added to substance
            • Heated
              • If it contains ammonium ions, it will give off ammonia
                • Damp red litmus paper turns blue
