A student loaded a mixture onto a small flash chromatography column in 1 mL of ethyl
acetate, then proceeded to elute with hexanes/ethyl acetate 10:1. He/she found that all of the mixture came off in the first 3 fractions, with no separation. What technical mistake did the student make?

a sample mixture of ethyl benzoate and dodecane is injected on two GC columns. Column A has DC710 silicone oild as the stationary phase, and column B uses polyethylene glycol as the stationary phase. Which substance would be certain to elute first from column A and would the same material be expected to elute first from column B? Which column, A or B, would be expected to give the better seperation of these two substances?

What would happen if you ran a flash (chromatography) column using a solvent where the Rf fo the lower spot was 0.5? What would happen if you ran a flash column where the Rf value of the upper spot was .2 and the Rf value of the lower spot was .05?

1) During this distillation experiment, a student collects a 10.00 mL fraction consisting of 70% ethyl acetate and 30% n-butyl acetate (by volume). What is the mole fraction of n-butyl acetate in this sample? 2) Suppose you used a shorter distilling column in this fractional distillation experiment. Would you expect to obtain a better or worse separation between the two esters explain your answer.

chemist performed the reaction shown below. He then wanted to separate the mixture using column chromatography. In his protocol he used silica as the stationary phase and a mixture of hexanes/ethyl acetate (75:25). Benzene -----> (HNO3/H2SO4) --> Nitrobenzene, Dinitrobenzene Trinitrobenzene 1. Assuming the reaction did not go to completion and starting material is present in addition to the three product, which fraction would contain which compound? Explain your answer. (4 pts) 2. What would be the consequence of changing the...

After fermentation, a mixture of ethanol and water is sent to a small distillation column. At the top of the distillation column, a 95% ethanol solution at 65°C is produced at a flow rate of 3.5 kg/s. Your job is to design a double-pipe heat exchanger that will cool the 95% ethanol mixture to 40°C by using cooling water that is available at 10°C. Assume an outlet temperature of the cooling water of 55°C, and only use Schedule 40 pipe...

Column Chromatography Lab 1. What would happen if diethyl ether were put in the column first instead of petroleum ether? 2. The recrystallization lab required you to purify naphthalene which contained a small portion of fluorenone. Could you use column chromatography to purify the same mixture? Would the selection of solvents be different from those used in this lab?
