    Food Dyes Lab

    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 times for the M&Ms as the color solution was not as strong as the food dyes. After the dyes were dry, I rolled the paper and added it to the pie plate, which contained a small amount of the prepared solvent. I then waited for the solution to…

    Food Dyes Lab

    Abstract: The 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; 100%, 80%, 60%, 40%, and 20%. The results for each dye were then plotted in a graph and a trendline was added. The slopes of the trendlines (y=mx) for red 40 and blue 1 were then used to determine the concentrations,…

    Colours In Kool-Aid

    Tetramethylammonium iodide was dissolved in a mixture of of Iodine and 95% ethanol while gently heated in a fume hood. Once cooled, crystals started to form in the beaker, which were then collected and washed with hexane through a series of processes involving vacuum filtration. Then a mixture of 5mh of the crystals and 5ml of 95% ethanol was created and tested on a slice of potato to analyse the iodine content. After, with sodium thiosulphate in the buret, the iodide solution was titrated until it turned orangey-yellow, then had 2ml of starch added to it and titrated again until it turned colourless.…

    Milk & Food Coloring Lab Report (Importance of Surfactant)

    Milk & Food Coloring Lab Report (Importance of Surfactant)

    Surfactant is an essential component for the respiratory system to function properly. Knowing the physiology of surfactant in the alveoli is important to know when learning the structure of the air sacs and how they work. This experiment is designed to make the understanding of surfactant in the alveolar film easier to learn, because it's not very simple. Surfactant is a detergent-like substance produced by the Type II alveolar cells in the walls of the alveoli. Surfactant is produced to reduce the surface tension of the water molecules that primarily compose the walls of the alveoli. For this experiment, we will be using milk and food coloring to represent the water (milk) and gas (food coloring) in the respiratory system, as seen in the liquid-gas boundary of the alveolar wall (water) and its volume (gas). We will place the milk in a shallow dish so that it completely covers the bottom of the dish. Drops of food coloring are going to be added into the milk at the center of the dish, and then observed. Drops of liquid dishwashing soap, representing surfactant, are then added to the center as well. Once the soap drops are added we will observe what changes happen to the food coloring and milk. Because I know milk is non-polar and food coloring is polar, my hypothesis predicts the two will not mix voluntarily at first, but the soap acting as a surfactant, when added, will help the two liquids mix together.…

    The purpose of this Lab is to use spectroscopy create graph to determine the concentration of dye in a sport drink, by creating series of standard dilutions of an FD&C Blue 1 Stock solution and measuring the percent transmittance of each dilutions. Results in each dilutions will be use, to determine the linear function among various functions (T, T%, log T, - logT) For a Beer’s law calibration curve. The produce provides a model for guided-inquiry analysis of the concentration of food dye(s) in sports drinks and other consumer beverages.…

    Chromatography: Food Coloring and Food Dyes

    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. When you eat food or drink liquids you are trying to get important chemicals to your cells. (chemicals that your cells might use for energy or maybe to build more cells.) Look at the food label below, though, and you’ll see a list of several chemicals that your cells cannot use. These chemicals may be added to keep the food from spoiling, give the food a flavor or texture that makes it taste better, or add color to the food/drink to make it look more appetizing so you will buy it. Many of the foods and drinks you buy each day would be clear or white without the addition of food dyes (artificial colorings).…

    Chemical Bleaching

    Australian government officials in the last few years have been taking the protection of the Great Barrier Reef into their own hands. After creating an eye on the reef program, which specifically targeted the health of the Great Barrier Reef, scientists created algae killing bleach that would be applied to infected sections of the reef. Practices worked well until 2014 after a double dose of the bleach. After many tourist encounters with the reef a few individuals took notice in the declining health over the reef. After reaching out to the Australian Government about the concerns United States Marine Biologists were informed that a “mass bleaching event is taking its toll on the Great Barrier Reef for an…
