A yellow compound, dissolved in methylene chloride, is added to a chromatography column. The elution is begun using petroleum ether as the solvent. After 6 L of solvent have passed through the column, the yellow band still has not traveled down the column appreciably. What should be done to make this experiment work better?

22 Experiment 2 Chromatography 32. A student properly sets up a column chromatography experiment. Although the mixture is soluble in the mobile phase, the sample appears "stuck" at the top of the column and will not elute regardless of how much solvent is applied. What could be the cause of this prob- lem and what could the student do to try and achieve a successful separation? NA disolves in #20 Salt No maybe the compound NASI is to much an the solvent being #20 is to little Vodafo 3. A student performs a separation by TLC on a silica get plate that results in three spots. A red spot is measured 23 mm away from the original sample spot, a blue spot is 42 mm away, and a yellow spot is 49 mm away. The distance from the original spot to where the solvent stopped is 55 mm. a) Calculate the Re value for each component in the mixture.

Consider four distinct physical properties: boiling point, melting point, solubility, and density. Which of these physical properties do you think allows thin layer chromatography (TLC) to work? Choose one then, explain your reasoning.
PAPER CROMATOGRAPHY • Define chromatography • Demonstrate an understanding of the process of chromatography • Describe the steps involved in a chromatography investigation Explanation Coloured inks are often made up of several different inks. Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup . Water • Scissors III. Health and safety • Make sure that you thoroughly clean any equipment after the experiment before using for food IV. Procedure Method 1 1. Take a sheet of kitchen roll and draw a simple picture with a non-washable felt tip pen. 2. Place the sheet over an empty bowl. This is to keep the paper from getting too wet. 3. Carefully add a few drops of water…

PART ONE: Preparation of FECNS* Solution Prepare the two solutions in table 1 by accurately measuring the required volumes of distilled water and CNS into two labeled test tubes. The absorbance of the solutions must be measured soon after adding the Fe" solution from a buret. TABLE 1 Fe 5 ml 5S mL Solution Distilled Water CNS 2 mL Total Volume 3 ml 2 ml 10 ml 3 mL 10 ml In this part of the experiment you are to explore what the above quote means. As a PRELIMINARY Exercise, formulate a hypothesis as to what would happen under each of the following circumstances: 1. 1ml of 0.0020 M CNS' solution is added to the unused portion of solution 1 in the test tube 2. One drop of 0.20 M CNS solution is added to the unused portion of solution 2 in the test tube.

2. A chromatographic column is eluted with a solution containing a mixture of two components, X and Y. The chemical affinity of X for the stationary phase is less than that of Y and the chemical affinity for X for the mobile is greater than that of Y. Which substance will be eluted first? Explain your answer.
2. What is the basis for the separation of components of mixtures by paperchromatography?
Which is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)
