In this experiment, what are the stationary phase and mobile phase, respectively? The stationary phase is the silica gel, and the mobile phase is the ferrocene and acetylferrocene mixture. The stationary phase is the silica gel, and the mobile phase is the solvent eluents. The stationary phase is the Pasteur pipet, and the mobile phase is the pipet bulb (to push the solvent through the column). The stationary phase is the silica gel, and the mobille phase is the molecules to be separated (ferrocene and acetylferrocene). Question 2 Why can ferrocene be eluted with hexane, while acetylferrocene can only be eluted with hexane/diethyl ether? Because ferrocene is stable in hexane, while acetylferrocene is only stable in hexane/diethyl ether mixed solvent. B Because acetylferrocene has a higher polarity than ferrocene, and it can only be eluted out with a polar Because acetylferrocene has a higher polarity than ferrocene, and it can anly be eluted out with a polar solvent. Because ferrocene has a smaller molar mass than acefylferrocene, making if easier to elute. Because ferrocene is soluble in hexane, but acetyiferrocene is not soluble in hexane. Question 3 Column chromatography can separate a mixtute of compounds by the differences in polarity and binding strength of the compounds to the adsorbents. molecular masses of the compounds. sofubilaty of compounds in the solvent. meiting points of the compounds.
