1. Is external force present to influence the analysis? Yes or No? 2. If the solvent is chloroform, which of the pigments is polar and non polar? 3. Compute the retention factor of the blue pigment. 4. Which of the pigments has the highest retention factor 5. What does a high retention factor imply in the analysis? The pigment of interest is well carried by the mobile phase. The pigment of interest is highly attracted to the stationary phase. The mobile phase is not suitable for extracting what is desired. The stationary phase warrants modification.

What property determines which layer is on top or bottom in an extraction? What are the values for 1‐ butanol, 1‐bromobutane and 1‐chlorobutane? Will the organic layer be on top or bottom? If you are not sure, how can you experimentally verify which layer is organic?
What would happen to the retention time of a compound if the following changes were made? 1.) Decrease the flow rate of the carrier gas 2.) Increase the temperature of the column 3.) Increase the length of the column
In the table below, record the color that you observe for each spot or component of each spot after the run is completed. For the retention factor, R₁, write in the numerator (top) the number of mm that the spot has moved and in the denominator (bottom) the number of mm that the solvent has moved from the point where the samples were 'spotted. Calculate the Rf vale for each spot or component of each spot. Im having a difficult time finding the Retention Factor for M&Ms by using Salt water and seeing how much each color moves Instructions Coffee filters usually are round, but it's easier to compare your results if the paper is rectangular. So, your first task is to cut the coffee filter into a rectangle. Measure and cut a 2-3/4" by 7" strip from the middle of a coffee filter. This is easily done by folding the filter in half (to make a half-circle) and then folding the half-circle into thirds. Cut along the 13-fold lines and trim the ends to make a rectangle. 2.

So I completing a lab report and one of the sections is on TLC analysis. In the experiment, the TLC plate was submerged in toluene ethylacetate and had spots of cinnamon leaf oil, cinnamon aldehyde, and cinnamon bark oil. 9 spots total were seen under the UV light, but different spots appeared following a vanillin stain. Why is this so and what does this mean?

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
