Background Information: When working in a lab‚ scientists often need to identify different molecules that are present in a sample they are studying. There are many ways to identify unknown molecules/chemicals in a sample. The method you will be using today is called Paper Chromatography and consists of 2 steps. First‚ you will separate the unknown chemicals and then you will identify

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two

exposed to pen ink Abstract To test the hypothesis that termites are more attracted to ballpoint pens than pencils‚ highlighters‚ and sharpies. A random-single termite was given out of a jar of termites and placed in a petri dish‚ which trapped the termite. Paper‚ pencils‚ pens‚ highlighters‚ and sharpies were also given out. Each group drew multiples circles on the paper with all 3 of the writing utensils. The circle the class used was shaded in halfway with paper mate pen ink and the other
