11. Why should you use pencil instead of pen when marking on a thin layer chromatography plate? a. Pencil lead isn't as dark. b. The components of pen ink will separate along with your sample, while pencil lead will not. c. Pen ink will not mark on a TLC plate. d. Pen ink will undergo a chemical reaction with the solvent. 12. Which of the following is not a reason to use thin-layer chromatography? a. To determine the number of...
Which of the following statements regarding thin layer chromatography are TRUE? Partition chromatography separates compounds based on how they distribute themselves between the stationary and mobile phases. In thin layer chromatography, a polar organic compound will be attracted to the adsorbent and therefore travel further up the plate than a non-polar compound The Rf value is independent of the adsorbent material used. In thin layer chromatography, a polar organic compound will be repelled by the adsorbent and therefore travel not...
Why is thin layer chromatography used to determine the purity of a sample when you could use an IR spectrum? How does TLC confirm the purity?
What are the advantages and disadvantages of thin-layer chromatography, adsorption column chromatography, and gas chromatography techniques? (advantages and disadvantages for each type)
Can you help me answer the questions for the Introduction/Background? 1. Introduced the techniques of thin-layer and flask column chromatography. Discuss how a solvent is elected as eluent. 2. Discuss all the applications of TLC. What is it used for? 3. Discuss the mobile and stationary phases of TLC and column chromatography. 4. Explain how column chromatography can be used to separate a mixture on a larger scale than TLC. Post-Lab: Objective State the objective of the experiment in your...
Wanting to monitor the reaction progress you decide to use normal phase thin-layer chromatography, but do not know what the best conditions are to use. If you had the standards for all potential products and your starting materials, outline how would you go about determining the best TLC conditions for monitoring the reaction progress. Provide drawings of an ideal TLC plate with the number of theoretical products you would expect and their relative positions. How do you know when the...
Is it possible to use Thin Layer Chromatography (TLC) to analyze a distillation sample. For instance, if I completed a Simple Distillation and wanted to find the identity of the distillate, would it be possible to do this through TLC? Please explain fully why or why not.
1. What is the purpose of Thin-Layer Chromatography (TLC)? D
List and describe the 4 steps of TLC (Thin-Layer Chromatography)
Thin Layer Chromatography: One spot with an RF of .62 is observed after you develop the TLC of a reaction mixture. Does this prove that you have only one product present? Explain.
