Number+11+Test+Results

We took the bag out and took samples and test them in a tray. We tested for Opites using Marquis Reagent and got negative results and them we tested for Coca Alkaloids using Co(SCN)2 and got a blue color and a positive match and then tested for Depressents using CO(C2H3O2) and got negative results and we tested for Otc Drugs using the Universal Indicator and FE(NO3) and got negative results aswell. We also tested for Other Substances and used HCL and Lugols solution and also got negative results. So the results we got was Coca Alkaloids. Oh and the other we person was Kierra Knight.

Crime Scene Evidence Report: My name is Jessica Anderson and I team partnered with Kierra Knight. I have been in Burrows 1st period Forensics class for 3 months.We were assigned the baggy number 11 which was a white powder. We did the testing in the lab available to the students. We tested the material on Tuesday March 13th at about 8:14am. We used the reagents Marquis for Opites and Co(SCN)2 for Coca Alkaloids, and Co(C2H3O2) for Depressents, and Universal Indicator and Fe(NO3) for Otc Drugs,HCL and Lugols solution for other substances. When we ran these tests we made sure that before and after each test we cleaned the tray out with distilled water and a scrub brush. We always kept our station clean so there would be no contamination. For each test a certain amount of drops from 3 to 6 was put in a tray containing a small sample of the unknown material. For each subject you test for there is a certain reagent specified to use to test it as i listed above. If the final results match the color or react the way they are known to do it is a positive match.Our only positive match was of a Coca Alkaloids. We know it is because it turned a blue color and under the Drug Test Quick Protocols chart it says it will turn blue. So our results are Coca Alkaloids.
