Description
I will give you the lab protocol and my results and I want you to answer the questions that left in the packet, It's an organic chemistry
"Thin Layered Chromatography, tlc lab"
It's easy though basic questions in the packet
Explanation & Answer
Hello! Please see the attached file. Let me know if you have questions.
Pre-Lab Questions:
1.
a.
b.
c.
d.
e.
Analgesics
Stationary phase. In TLC, the stationary phase is silica gel (silicates)
Thin-Layer Chromatography
Origin
Solvent front
2. To avoid/prevent tailing of spots, as well as, smudging.
3. Error 1: Chromatographic chamber does not have a cover (mobile phase might
evaporate and affect the analysis)
Error 2: TLC plate does not have a solvent front.
4. Rf, A = 3.56 cm / 8.98 cm = 0.396
Rf, B = 6.76 cm / 8.98 cm = 0.753
Part B:
Mystery of analgesic sample ID: ________________
Analgesics in the sample: Caffeine
Identity of the analgesic: Caffeine
