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.

I know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!
In normal phase TLC, the mobile phase is + polar than the stationary phase. Consider the TLC plate below, which was developed using a 25% ethyl acetate:hexane solution. If this same mixture of compounds was developed on a TLC using a 50% ethyl acetate:hexane solution, the orange spot would A mixture of two compounds was developed on a TLC plate. The result is shown below. What is one thing the chemist can do to get better results? In normal phase TLC, the mobile phase is : polar than the stationary phase.

How do you know if the ethyl acetate you get at the end of the experiment is pure?A)We add water, if it mixes, it is pure,B)If we see two spots when we look at TLC, it is naive,C)We look at the boiling point,D)We add desiccant, if it doesn't stick to the bottom of the beaker, it is pure,E)We look at the smell,
3. The TLC technique can be used to: a. Check the purity of a compound. b. Determine the number of components in a mixture. c. Purify large amounts of a compound. d. Check the identity of a compound all of the above b and d a and d a and b a, b and d
Using figures 3 and 4 in the lab manual, rank each compound according to their polarity. For the least polar molecule, draw the structure and label any important functional groups on the molecule.
Conclusion 5: You are tasked with analyzing a suspiciously pink sample of drinking water to establish if it has unsavory levels of MnO4-contamination. It has an absorbance of 0.83 at 544 nm when measured in a cuvette that is 1 cm across. Using the equation of your trend line from Plot 4, determine the concentration of KMnO4 in moles/liter. Convert this concentration to grams of manganese/liter and compare it to the EPA guideline above. Trandline is Absorbtion = 2000(Concentration KMnO4) (Y=Mx)
