A sample is run on a TLC plate and gives a single spot as shown below on the left. However, the solvent was not allowed to run up the plate very far, and so the experiment was repeated with a much larger solvent distance as shown on the right below. What would be the approximate Rf value of the spot for the repeat experiment on the right? solvent line solvent line start line start line 01.0 0.9 © 0.5 0.1

The TLC plates below show authentic samples of salicylic acid in the left lane and student product in the right lane. The plate on the left was run in 50:50 hexane:ethyl acetate, and the plate on the right was run in 50:50 hexane:ethyl acetate plus a single drop of acetic acid in the solvent. Calculate the Rf of salicylic acid on the LEFT-HAND PLATE ONLY. Report your answer to two significant figures. 6mm 50:50 41 mah 6mm (45 mm 11:1 11.5mm 50:50 Idrop glacial a.a.

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.

if you perform QC for sodium on a chemistry analyzer and the value is greater than 2SD above the mean. This is the second day that this level of control has been >2SD for that analyte. You mixed the vial and repeated. QC was still "out". It is time to troubleshoot. What do you do?
A reaction mixture spotted on the TLC plate has been refluxing for one hour. There is a single organic product of the reaction. After 1 hour a student elutes a TLC plate of the starting material(s) (SM), the known product (P) and the reaction mixture (RM). Based on the TLC below, do you think the reaction should be refluxed further? Explain your answer. SM+ P + RM+ O O O
