Homework Help: Flame Test Lab Colors

  1. Dec 8, 2008 #1
    1. The problem statement, all variables and given/known data
    Checking the before and after of ions of various elements for the flame test.

    2. Relevant equations
    None really.

    3. The attempt at a solution
    I looked online for the elements but am not sure the data is correct/accurate enough.
    So far I have:
    Aluminum-Grey/clear-No color, more or less, or white
    Ammonium-White cloud/Clear-No color
    Barium-Silver/White cloud-Green (apple green)
    Calcium-Clear/Silver/White cloud-Brick red/orange/yellow-orange
    Cobalt (II)-Red-Pink/Blue
    Copper (II)-Turquoise-Blue/Turquoise
    Iron (III)-Orange-brown/Yellow/Pale purple-Gold
    Lithium-Clear-Crimson red
    Manganese (II)-Slightly brown-Yellowish green/silver/no color
    Zinc-Clear/Slightly brown-Bluish green

    I would like the data to be verified, or at least part of it, particularly the before colors that are white/clear

    What do you mean by "before" - color of the ion in the solution?

    Yes before is the color of the ion. It would be how the liquid looks before put into the flame. The colors for before, for most of them, the color that I observed of the liquids, but I'm not sure they are described accurately enough.
