(2) Sally starts eluting her column with petroleum ether in hopes of separating her 50:50 ferrocene: fluorenone mixture. She notices her mobile phase getting low when there is limited separation between her two components. She eagerly adds more solvent to avoid her column from drying out. Sally then realizes she poured from her 1:1 petroleum ether: diethyl ether beaker rather than her petroleum ether beaker. (a) Using the molecular view below, explain how this would impact her product elution from the column. top of column -- buret wall Al UU Al O: 0: AI :0: H H buret wall bottom of column (b) How does this error impact her experimental results? (c) Using pictures and words, how could Sally analyze the purity of her product?
