Chromatography lab Purpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper, Food coloring, Ruler, Pencil, Solvent solution, Test tubes, Test tube rack. Safety precaution: wear aprons, to make sure that you don’t get any of the alcohol on your clothes, and if you break a test tube you don’t get glass on you. Procedure: See-attached handout. Results: See chromatography with Audrey’s lab report.

Discussion/Conclusion: In this chromatography lab, we separated food coloring into their component dyes using chromatography paper. When we put the piece of chromatography paper in the solvent, the paper absorbs that liquid due to capillary action. The basic colors of the ink spot will separate out into bands, and you can see the different colors that are in the ink to produce that specific color. The smallest molecules will travel basically at the same rate the solvent travels up the chromatography paper. The larger molecules will travel slowly and will stay near the bottom. Our results of our experiment were a little different then the other groups. We all matched only a couple of the Rf values, but some of our distances were a little different. We probably took our chromatography paper out before or a little later then some people, because not all of our colors were had the same measurement. It would be interesting to try using a different kind of solvent to see how much of a difference it makes when the colors separate, because our blue never really separated into the different colors that make it. It would be cool to see either if you need to use a difference solvent or leave the chromatography paper in the solvent longer then weShow MoreRelatedLab Report On Chromatography And Lab1206 Words   |  5 PagesColumn Chromatography and TLC of Spinach Group Experiment 3 – Individual Lab Report (Save as pdf and submit, due by 12:00 NOON one week after experiment) Last Name: Wang First Name: Zoey Lab Partner(s): Sue Wang TA Name: Sosthene Date Lab Performed: Nov. 12, 2015 Date Lab Submitted: Nov. 12, 2015 Group A, B, or C: B Comments for Grading TA: (Please indicate if you performed the lab on a day other than your regularly scheduled day and/or with a TA other than your regular TA).

Gas chromatography allows for analysis of these complex mixtures that is then utilized by fields like beer manufacturing and forensics. The analytical method involves the use of a device to measure the separation of a volatile substance in which each component of the mixture possesses a unique volatile range. It depends on the solubility and the boiling point propertiesRead MoreLab Report : Fractional Distillation And Gas Chromatography1317 Words   |  6 PagesLAB REPORT I: FRACTIONAL DISTILLATION AND GAS CHROMATOGRAPHY INTRODUCTION The purpose of this lab is to investigate the processes that can be used to separate two volatile liquids in a mixture based on their chemical properties. This is accomplished by fractional distillation, which separates chemicals in a mixture by differentiating them by their boiling points at atmospheric pressure. Specifically in this lab, fractional distillation is used to separate an unknown mixture into its respective pureRead MoreFractional Distillation And Gas Chromatography Lab Report1644 Words   |  7 PagesFractional Distillation and Gas Chromatography Lab Report Introduction: Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points. During this lab, students were given 30 mL of an unknown solution containing two colorless chemicals. Because the chemicals may have had a relatively close boiling point, we had to employ a fractional distillation over a simple distillation. By adding a fractionating column between the boiling flask and the condenserRead MoreThin Layer Chromatography Lab Report1791 Words   |  8 Pagesplaced on the first â€Å"X†, a spot of Benzophenone solution was placed on the second â€Å"X†, a spot of Benzhydrol solution was placed on the third â€Å"X† spot and a spot of the unknown was placed on the last â€Å"X†.
