22 Experiment 2 Chromatography 32. A student properly sets up a column chromatography experiment. Although the mixture is soluble in the mobile phase, the sample appears "stuck" at the top of the column and will not elute regardless of how much solvent is applied. What could be the cause of this prob- lem and what could the student do to try and achieve a successful separation? NA disolves in #20 Salt No maybe the compound NASI is to much an the solvent being #20 is to little Vodafo 3. A student performs a separation by TLC on a silica get plate that results in three spots. A red spot is measured 23 mm away from the original sample spot, a blue spot is 42 mm away, and a yellow spot is 49 mm away. The distance from the original spot to where the solvent stopped is 55 mm. a) Calculate the Re value for each component in the mixture. (Show your work and report the correct number of significant figures.) highest polarity. Explain your answer. b) The silica gel plate is polar. Rank the three…
5. What would be the effect of the following errors in chromatographic work? a. The solvent level in the developing chamber or beaker is higher than the spotted sample b. Too much sample is applied to the paper or plate C. Sample spots are too close to each other d. The paper or plate is allowed to remain in the chamber after the solvent front has reached the top of the paper or plate 6. Differentiate normal phase chromatography from reverse phase chromatography. From which of the two governs the video demonstration in TLC and paper chromatography? How do you say so?
