Purpose:
Determine whether unknown substances are Cocaine or LSD by using reagents.
Procedure:
Pour a sample and determine the pH with pH paper, using reagents and the colors they turn determine whether they are cocaine or LSD
Data:
Drug | pH | Cocaine Reag. “blue” | LSD Reag. “Yellow” |
1 | 6 | + | - |
2 | 9 | + | - |
3 | 3 | - | + |
4 | 7.5 | + | - |
5 | 6 | + | - |
6 | 5 | - | + |
Research:
Cocaine
Chemical Name: benzoylmethylecgonine
Chemical Formula: C17H21NO4
pH: 8
Biochemical Tests: chromatographic techniques can easily distinguish and separately measure each of these substances
LSD
Chemical Name: Lysergic acid diethylamide
Chemical Formula: C20H25N3O
pH: 4
Biochemical Tests: comparing the hallucinogen LSD with lisuride, a structurally similar drug that also acts on serotonin or 5HT2A receptors but is not hallucinogenic
Methamph
Chemical Name: methylamphetamine
pH: 12.8
Biochemical Tests: Gas chromatography-mass spectrometry and photoemission spectroscopy
Conclusion:
We successfully differentiated which drugs tested positive for LSD and which ones tested positive for crack cocaine.
I liked the chart you used to really show your lab. I also like how you gave info about each drug.
ReplyDeleteThis is really organized and explains the lab very well. A picture or two might help even more.
ReplyDeleteI like the chart a lot because it's really helpful to see what went on in the lab, and also the fact that you made it like our lab notebook was helpful with the procedures.
