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

In this experiment the objective is to separate dyes in washable markers to see how many different dyes are combined to create one color. The technique used to separate the dyes in this 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

_______ Training Lab: Paper Chromatography I. Background Information: When working in a lab‚ scientists often need to identify different molecules that are present in a sample they are studying. There are many ways to identify unknown molecules/chemicals in a sample. The method you will be using today is called Paper Chromatography and consists of 2 steps. First‚ you will separate the unknown chemicals and then you will identify them. This process can also be applied to the food we eat everyday.

Lab Two; Chromatography of Food Dyes Jan Konig 28.04.2013 11:00am Chemistry 121‚ section DE Abstract: The second lab deals with the chromatography of food dyes which means you figure out what kind of compounds are used in a product like food color etc. by comparing the result to FD&C Food Dyes. You use six different food dyes‚ four food colors out of the store‚ two different Kool Aid powder and four different colors of candy like M&Ms you use for the chromatograph. At the end you try

The Chromatography of Food Dyes and determination Of the Dyes Present in M&M Candies Procedure To complete this lab‚ I first mixed the solvent solution consisting of the proper ratio of water‚ salt‚ and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing‚ with a pencil‚ the appropriate lines and labels. Using a toothpick‚ I added the color to the paper‚ and then repeated until the color was strong. I repeated this step several more

determined by using Chromatography. The components of a mixture have different affinities for a stationary phase as well as different affinities for a mobile phase. INTRODUCTION An extremely common technique by using two chemicals and filter paper can give you sufficient information. A well-done Chromatography of dyes will provide you with enough data to determine if a liquid mixture is heterogeneous or homogenous . In a learning activity you can separate and possibly identify food dyes in some drinks

purpose of this lab was to determine the food dyes present in a selected beverage‚ their concentration‚ and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage‚ red 40 and blue 1 were determined to be present. The next step was to determine the concentration of the dyes‚ this was done by testing the absorbance of the red 40 and blue 1 dyes at varying concentrations;

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.

Title Testing Kool-Aid Mix for Food Dye Additives Purpose What food dye additives go into the food products we consume and how do these additives affect our perception of that food? Hypothesis If “Black Cherry” flavored Kool-Aid Mix appears red‚ then it will contain the food dye additive Red-40 that emits a red pigment. Background Food color not only affects the appearance of food‚ it also affects our perception of how food tastes. Tests have shown that consumers will choose colored drinks over
