  • Does flame emission spectroscopy work for mixtures?
    yes
  • Describe flame emission spectroscopy.
    sample placed in flame
    ions heat up and electrons become excited
    when electrons drop back to original energy levels they transfer energy as light
    light passes through spectroscope which differentiates wavelengths
    line spectrum produced
  • Intensity of spectrum indicates concentration of ion in solution.
  • Flame emission spectroscopy can be used to calculate concentrations as well as ions present
  • Machines can analyse unknown substances.
  • Give advantages of using machines for instrumental analysis
    Very sensitive
    Very fast
    Very accurate
