QUESTIONS 1) How will the following affect the TLC separation? a) too much sample applied. b) Stationary phase is too active. c) Forgetting to remove the plate when the solvent has reached the top of the plate. d) Having too much solvent in the developing chamber so that its surface extends above the origin. e) Polarity of the solvent being too high. 2) Which dye would be more soluble in n-propyl alcohol, the blue or the yellow? How can you tell? 3) Which compound is more strongly adsorbed on silica, ortho- or para- nitroaniline? Correlate the R, values with the structures.

Task: You are a forensic analyst employed at the Baltimore County Forensic Lab. You plan to perform paper chromatography on the ink from the note and a sample from the marker. Permanent marker ink is non-polar. You need to select the best solvent to use as the mobile phase in order to compare the ink sample and determine if they may be a match. The solvents you have available to you are carbon tetrachloride and water.Which solvent would be best to analyze the ink samples using paper chromotography?Your explanation should include:• the name of the liquid solvent that should be used for the paper chromatography analysis• scientific reasoning for your choice of the liquid solvent that will be used• the Lewis structures for carbon tetrachloride, CCl4, and water, H2O• how the shape and symmetry of each molecule influences its polarity
A mixture of tert-butylbenzene and acetophenone is adsorbed onto a silica gel chromatography column and eluted with a moderately polar solvent such as dichloromethane. Match each statement to the appropriate category. least polar tert-Butylbenzene elutes first most polar elutes last Answer Bank Acetophenone

Plant pigments in spinach were separated with TLC with cellulose as thestationary phase and 80/20 diethyl ether/acetone mixture as themobile phase. If needed, the solvent structures in the lab Appendix.1. Determine the Rf values of each plant component on this TLC plate.2. Arrange the plant components from most polar to most nonpolar. Please answer both 1 and 2 (picture below is the same question attached )
There were 2 spots on the TLC that did not match up with any of the standards. What were the Rf values of these spots? Identify what these chemical species might be and draw their structures. Solvent was 3:1:1 n-butanol/acetic acid/water. First plate is TLC plate 1. Second plate is TLC plate 2.

QUESTION 15 To improve the accuracy of our linear fit between absorbance and concentration, a. add an extra data point to your linear regression where you make the assumption that pure water has an absorbance of zero. b. make sure that you choose a "Linear Regression" curve fit. c. ensure that there are no air bubbles in the cuvette. O d. use the data points only at the lower end of the concentration range because Beer's Law is not applicable for higher concentrations.
