Flame test identification- metals?

  1. Jan 16, 2012 #1
    Flame tests are used to test the color that a metal produces when heated and the electrons release energy when falling back to the ground state. This i understand, but why does the procedure only test the metal part of the salt? In other words, why does the anion part of the ionic compound not effect the flame color?

    In theory it could, it just happens that most anions don't emit visible light. I doubt it is more than just a coincidence.
