Flame Tests

• Using flame tests to identify metal ions:

  • Place a small amount of the chemical into wire mounted in a handle
  • Place the end of the handle into a blue bunsen burner flame
  • The flame colour can be used to work out the metal ion present

  Lithium ions produce a scarlet flame test.

  Sodium ions produce a yellow flame test.

  Potassium ions produce a lilac flame test.

  Calcium ions produce an orange-red flame test.

  Copper ions produce a green flame test.
