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

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

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

Column and Thin Layer Chromatography: The Separation of Spinach Pigment Abstract Spinach extract was separated into fractions containing compounds of similar polarity by column chromatography. Based on solid-liquid phase partitioning‚ this separation technique exploited the different polarity of the compounds in the spinach extract. Three fractions with different colors were obtained. The extract and its fractions were analyzed using thin layer chromatography (TLC). The TLC results showed that

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

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

Lettuce Salmon Wraps If you want a hearty‚ tasty treat to enjoy‚ you’ll find that this will be one of the best meals for you! You can add a bit of tofu into the mix if you prefer‚ but raw fish is the ingredient that will be added in this recipe. You’ll have to make sure that it’s very fresh‚ as raw fish can be dangerous if not eaten immediately. Ingredients: For this dish‚ you will need: 1 carrot 1 mango 4 ounces of salmon 1 cup of raw almond butter ½ head of cabbage 2 lemons ¼ cup of
