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

Objectives: To use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions:

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their

Wickler is actually responsible for the usage of 40% now. Secondly‚ Wickler should only consider taking on the product of energy gel in the first place if it will still be profitable while including the costs of the necessary machinery. According to the projections in the financial statements‚ it seems as if they will exceed capacity of the machines between the energy bars and gels together. Even more so then Wickler must consider machinery as a cost of his. Also‚ we believe he should be taking into
