Flame Test Lab #4
FBI Investigators,
My partner and I, here at the Geauga County Crime Lab, have come to the conclusion that all of the unknown substances found at the scene are in fact metal salts. We have compared these four found substances to our 7 known metal salt solutions. After much careful observation, we have come to the conclusion that substance A is Lithium (Li), B is Potassium (K), C is Calcium (Ca), and D is Strontium (Sr). Due to the fact that substance A showed a red/violet color, just as LiNO3 did, we came to the conclusion that it was Lithium. Likewise, since B showed a indigo/orange/violet color just as KCl had, we decided that it must be Potassium. Since C was an extremely bright orange color, we have decided that it is most likely Calcium (like in CaCl2). Lastly, we have come to the conclusion that substance D is Strontium due to it's bright red color, just as the color produced by SrCl2. We hope that this information will aid you in your investigation.
