What physical property of the FD&C dyes is the basis of the resolutions you will perform in this experiment? the dyes' ability to dissolve in the stationary phase of the ssystem the dyes' color The dyes' ability to dissolve in the mobile phase of the system The dyes' relative attractions to the stationary and mobile phases of the chromatography system QUESTION 4 What is the problem created if you mark the origin line with a washable felt-tip marker? There is no correct answer The samples dyes would not move from their original place on the paper and would be suspended The dyes in the ink from the felt-tip marker would be separated Nothing out of the ordinary would happen, the dyes from the sample would be clearly resolved QUESTION S What is the problem created if you do not remove your chromatogram unti aher you discover that the solvent front has reached the top of the paper? The solvent will begin to evaporate and the sample could be lost The Rf values cannot be determined accurately. because it is impossible to compare the movement of individual spots with the final position of the solvent front The chromatogram may stick to the bottom of the beaker or to solvent chamber The Rf values can still be determined very accurately but it is impossible to compare the movement of individual spots with the final position of the solvent front QUESTION 6 0.2 Using the chromatogram shown for pre-lab question 4 in your laboratory manual, measure the distance the solvent front has moved in centimeters) 000
