Introduction- The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Features. Flame Test of Ions, including Li, Na, K, Sr, Cu, and an unknown. Record your observations in your notebook and use the results of the previous tests to determine which metal ions (if any) are present in the unknown crystals. In order to identify the unknowns, the flame colors were. Purpose: The purpose of this lab was to observe the characteristic colors produced by certain metallic ions when vaporized in a flame. When there is an unknown compound, the metal can be found by using previous data from previous tests. Primarily, the flame test detects the presence of metalions in a compound, and as ions of each element have a specific characteristicbased in their emission spectrum, the flame test for every element is differentand distinctive. The purpose of the lab is to observe the characteristic colors produced by certain metallic ions when vaporized in a flame. ... another element in a ratio of small whole numbers. You can use the colour of the flame to work out what metal you have in your sample.
