Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

com Liquid Chromatography AP Chemistry Laboratory # 18 Publication No. 10535A Catalog No. AP9093 Introduction In this experiment‚ liquid chromatography is used to separate the substances that are present in grape-flavored Kool-Aid®. First‚ the dyes responsible for the purple color‚ FD&C Blue #1 and Red #40 are separated. Then‚ in a second experiment‚ the other components of Kool-Aid®‚ the flavorings and citric acid‚ are separated as well. Concepts • Resolution • Liquid chromatography • Selectivity

The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

OBJECTIVE The purpose of this experiment is to analyze mixtures of compounds prior to‚ during and after a separation scheme. This experiment also allows monitoring reactions of organic molecules‚ and determines the identity of a mixture of compounds. STRUCTURES AND PHYSICAL PROPERTIES OF REACTANTS [1] SOLVENTS | a.

Gabriel Alizaidy Liquid Chromatography September 14‚ 2009 Objective: To separate the components of unsweetened‚ grape flavored Kool-Aid. Procedure: Using two syringes‚ inject different concentrations of alcohol to extract red and blue dyes‚ and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography‚ resolution and selectivity played major roles in making the experiment work

Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

experiment is called chromatography. The materials used consisted of – 3 pieces of chromatography paper‚ a tall clear glass‚ water‚ table salt‚ 1 tsp. measuring spoon‚ an 8 oz. measuring cup‚ pencil‚ ruler‚ 6 washable markers‚ and paper towels. The markers used in this experiment have to be water soluble therefore I used washable markers made by Crayola. The colors I chose were brown‚ teal‚ red‚ orange‚ black‚ and green. The salt solution served as the mobile phase while the chromatography paper served

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method
