unknown compound. In this experiment‚ chromatography and titration were performed to identify the unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile

Density Column What is density? We will be working with many different liquids. Each of the liquids has a different‚ characteristic density. One way to think about density is how thick or heavy an object is. The liquids with lighter densities will float. The liquids with heavier densities will drop to the bottom. You may have noticed that sometimes‚ liquids mix together – this is because the chemicals dissolve in each other. During our experiment‚ the liquids will stay separate because we will

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

Chromatography of Food Dye Chem 180-DL3 Abstract: The goal of this experiment was to use different dyes to determine the Rf value. Chromatography is done to determine the presence of a mixture in a substance. In this experiment different dyes were used such as McCormick food coloring‚ M&M’s‚ Kool-Aid‚ and the dyes that came with the lab kit. Experiment and Observation: In this experiment a 50mL beaker was filled with luke warm water and a pinch of salt water was dissolved in it

CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C

Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy
