Conclusion PAPER CROMATOGRAPHY• Define chromatography• Demonstrate an understanding of the process ofchromatography• Describe the steps involved in a chromatographyinvestigationExplanationColoured inks are often made up of several different inks.Each colour of ink will get carried a different distance by thewater, allowing you to see all of the different inks. Try this withdifferent colours to see what actually goes into a colour. Thistechnique is called chromatography and can be used inchemistry to find out what is in an unknown mixture.II.

Take a sheet of kitchen roll and draw a simple picture with anon-washable felt tip pen.2. Place the sheet over an empty bowl. This is to keep the paperfrom getting too wet.3.

You obtain an Unknown Sample from the Stockroom. You begin testing the solution through the steps outlined in the flowchart of the experiment’s PDF file. You first add HCl and centrifuge your mixture. You observe the formation of a white precipitate in the bottom of the test tube. After pouring off the supernatant liquid, you add hot water to the white precipitate. Upon addition of the hot water, you have some white precipitate still at the bottom of the test tube, and the supernatant liquid is poured off. To this liquid, potassium chromate (K2CrO4) is added. Upon this addition of potassium chromate, you observe no formation of precipitate. Which of the following is a valid conclusion to draw at this point? (Choose one.) Select one: 1. Hg22+ is definitely present. 2. Pb2+ is NOT present. 3. Ag+ is definitely present. 4. Pb2+ is definitely present.

One method for the quantitative determination of the concentration of constituents in a sample analyzed by gas chromatography is area normalization. Here, complete elution of all the sample constituents is necessary. The area of each peak is then measured and corrected for differences in detector response to the different eluates. This correction involves dividing the area by an empirically determined correction factor. The concentration of the analyte is found from the ratio of its corrected area to the total corrected area of all peaks. For a chromatogram containing three peaks, the relative areas were found to be 16.4, 45.2 and 30.2, in order of increasing retention time. Calculate the percentage of each compound if the relative detector responses were 0.60, 0.78 and 0.88, respectively.

Consider the following statements as they apply to gas chromatography. Decide if each is true or false. 1. ___ Temperature programming is necessary only for samples containing compounds with a narrow range of boiling points. 2. ___ GC carrier gases are generally inert gases like helium and nitrogen. 3. ___ The injection port temperature should be set at the average boiling point of all analytes. 4. ___ An FID is a mass-sensitive detector, not a concentration-sensitive device. 5. ___ An air peak is commonly used to determine the dead time when using an FID detector.
A scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.37 mg/mL of methyl benzoate (peak A) and 1.51 mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 3.40×102 and the area of peak B is determined to be 398 measured in arbitrary units by the computer. To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.49 mg/mL is mixed with 1.00 mL of the plant stream material. Analysis of the mixture gave a peak area of 437 for peak A and 415 for peak B. What is the concentration of methyl benzoate in the plant stream?
