A student performed chromatography on a mixture of benzoic acid (C₂H5CO₂H), acetophenone (C6H5C(O)CH3) and styrene (C₂H5CHCH₂). She used alumina (Al2O3) as the stationary phase and a 9 : 1 mixture of hexane : ethyl ethanoate as the mobile phase. Rank the order in which the compounds moved, from fastest to slowest. < benzoic acid acetophenone styrene

Classify the descriptions based on whether they apply to ion‑exchange, size‑exclusion, or both types of chromatography columns. - Proteins move through the column at rates determined by their net charge. - The gel bed will contain polymer beads with charged functional groups. - Proteins move through the column at rates determined by their size. - The gel bed will contain porous polymer beads. - The properties of the proteins affect the rate at which they migrate. - Proteins are separated based on differences in their amino acid sequences.
Amino acids and fatty acids do not readily elute from gas chromatography columns even at temperatures above 200 degrees Celsius. What can be done to these biomolecules to allow gas chromatographic analysis?
An unretained solute is eluted from a GC column in 1.80 min. Decane (C10H22) is eluted in 15.63 min and undecan (C11H24) is eluted in 17.22 min. What is the retention time (report to 2 decimal places, in minutes) of a compound whose retention index is 1050?
1a) Hexane, CH3(CH2)4CH3, is found to have a long retention time when separated from a mixture. A column with a C18 (18-carbon chain) stationary phase and a methanol-water modal phase is used for the separation. Explain why hexane has a long retention time. 1b)You wish to chromatographically seperate a mixtureof the follwing compunds. Which of the two compounds will be most difficult to seperatate from one another? Why?
Please answer Questions 5-3, 5-4, and 5-5 (GC Gas Chromatography) 5-2. A sample mixture of ethyl benzoate (bp 212 Celsius) and dodecane (bp 216.2 Celsius) is injected on two GC columns.Column A has DC710 silicone oil as the stationary phase, and column B uses polyethylene glycol as the stationaryphase. Which substance would be certain to elute first from column A and would the same material be expected toelute first from column B? Which column, A or B, would be expected to give the better separation of these two substances? 5-3. Question 5-2 refers to separating a mixture of two high boiling liquids by gas chromatography. These materials havesimilar boiling points. List several GC variables and conditions that would make it easier to separate thesesubstances by gas chromatography. 5-4. Capillary GC columns have better resolution than packed columns even though the enormous surface area provided by the packing material is absent in capillary columns. Why? 5-5. Preparative GC requires…
Upon screening with TLC (made of silica gel) chromatography using hexane/chloroform (3:1) as eluting solution, 3 spots were detected corresponding to a (A) polyphenol, a (B) tannin and an (C) alkaloid. Write the letters of your answers on the spots in the chromatogram shown at the right.

Oral rehydration salts are stated to contain the following components: Sodium Chloride 3.5g Potassium Chloride 1.5g Sodium Citrate 2.9g Anhydrous Glucose 20.0g 8.342 g of oral rehydration salts are dissolved in 500 ml of water. 5 ml of the solution is diluted to 100 ml and then 5 ml is taken from the diluted sample and is diluted to 100 ml. The sodium content of the sample is then determined by flame photometry. The sodium salts used to prepare the mixture were: Trisodium citrate hydrate (C6H5Na3O7, 2H2O) MW 294.1 and sodium chloride (NaCl) NW 58.5. Atomic weight of Na = 23. The content of Na in the diluted sample was determined to be 0.3210 mg/100 ml. Determine the % of stated content of Na in the sample. The stated should be 104.5, how??
