Unformatted text preview: Atif Saleem, Chem 3AL, Section 101 Discussion: Experiment 7, Thin Layer Chromatography My group consisted of Emma, Jafar, Rachana, and I. The criteria that we used as a group to narrow down the choice of our TLC solvents in Part II consisted of the solvents that gave us the best separation on the plates of already known compounds. We defined the “best separation” as the plates on which a solvent allowed the known compounds to clearly separate away from each other. Jafar and Emma’s solvents exhibited this property the best and their solvents were 100 % Ethyl Acetate and 10:10:1 toluene: ethyl acetate: acetic acid respectively. These solvents showed good polarities, so we chose them to be our solvents for Part II. The way in which our group identified the unknown analgesic was by first using the solvents we determined previously as good candidates. After determining which solvents provided the best separation, we received an unknown solid W which we crushed and added 0.5 mL of ethanol to. (Our solid’s initial property included that it was insoluble in ethanol). We split mL of ethanol to....
