Test tube 1-7 should be mixed to get first compound as all these test tubes contains single spot means single compound.
Test tube 11-21 should be mixed to get second compound again same reason single spot.
Test tube 25-31 should be mixed to get third compound again same reason.
Donot use test tube 9 and 23 as they contain 2 spots that means two compounds and we are not certain about test tube 8 and 22 for these 2 test tubes we need to take TLC to confirm whether they contain single spot or not.
8.5 TLC is commonly employed with column chromatography to monitor the separation of colorless compounds. The...
what is the prediction of the unknown amino acids mixture based on the strip from thin layer chromatography sheet? The unknown mixtures can be ala plus asp, ala plus asp plus lys, lys plus asp or ala plus lys. anion exchange resin was used Tubes 2,3, 6 and 7 had a spot appear that was light pink We were unable to transcribe this imageWe were unable to transcribe this imageH-) to the column followed by a sufficient amount of the...
if applicacable, please write clear stepwise mechanism for all synthetic transformations, showing important internediates where appropriate. only do this if applicable for this lab. Experiment SD Column Chromatography Running the Reaction. Once sodium borohydride has been added to the reaction meture Isee next paragraph take samples at the times just indicated. Because this must be done in such a short time you must be well prepared before starting the reaction. One person should be the timekeeper, and the other person...
Attached is the lab experiment. Here are the questions I need help with: 1. What is the purpose of each of the following steps in this experiment? a. Adding solid NaCl to the reaction mixture b. Repeated washings with water, sat'd NAHCO3, and brine c. the pipet column chromatography 2. Which compound, cyclohexanol or cyclohexanone will have a higher Rf on a TLC plate? 3. What is the advantage of using sodium hypochlorite as an oxidant over CrO3 or Na2Cr2O7...
1 - Provide a balanced equation for this reaction 2 - Provide a mechanism for the transformation of cyclohexanol into cyclohexanone 3 - Provide a flow chart for the workup procedure for isolating cyclohexane from all the by-products, making sure to note in which layer you expect to find your product in each extraction. 4 - Provide the theoretical yield of cyclohexane in this experiment. PROCEDURE OXIDATION OF CYCLOHEXANOL TO CYCLOHEXANONE Set up a water bath as the heat source...
2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
