Aim:

The aim of the experiment that was carried out was to see, at what temperature and in which standard solution, does the amount of dye left in the boiling tube had the highest percentage transmission. Beetroot was used for the experiment because it was easier to see the dye after the practical was completed. Putting beetroot cylinders into different boiling tubes, which contained three different standard solutions of Ethanol, they were left for half an hour at a certain temperature to get the dye out. Once the time was up, the solutions was added to cuvettes and inserted into the colorimeter to test how much light was passed through the sample.

Preliminary Work:

    Determining the Concentrations of Red Dye in Sodas

    In order to create a standard curve we created 5 dilutions of solutions containing red dye #40. Concentrations of .666 ug/mL, 1.667ug/mL, 3.333ug/mL, 13.333ug/mL, and 20.000 were measured in a spectrophotometer set to a wavelength of 504 nm to find the amount of light they absorbed. Using Microsoft Excel, we entered the absorbance values as the Y coordinates and the concentrations as the X coordinates to make a line of best fit and that was our standard curve.…

    Food Dyes Lab

    The initial step to determine the concentration of the dyes previously found was to prepare a set of serial dilutions at 20%/40%/60%/80%/100% dye concentration. To prepare the 20% dilution 1mL of red 40/blue 1 was combined with 4mL of DI water. This method was used to produce the remaining dilutions with 2mL/3mL, 3mL/2mL, 4mL/1mL, and 5mL/0mL (mL dye / mL DI water). Each of the previous dilutions was tested in the spectrometer and data was recorded. Using the data obtained two Beer Law plots were plotted for both dyes and trendlines were added. The slope of the trendline was found and used to calculate the actual (mol/L) and percent concentrations…

    Peroxidase Lab

    The materials needed for this experiment were four medium sized tubes, a spectrophotometer, a buffer with a pH of 5, H2O2, Peroxidase, and Guaiacol Dye. We as a group had four tubes labeled two, three, four, and five. In the tube labeled two we had a solution of 2.0 mL of H2O2 and 1.0 mL of Guaiacol Dye for a total solution of 3.0 mL. In the tube labeled three we had a solution of 4.0 mL buffer and 1.0 mL Peroxidase for a total of 5.0 mL solution. In the tube labeled four we had a solution of 2.0 mL H2O2 and 1.0 mL Guaiacol Dye for a total of 3.0 mL solution. Last, in the tube labeled five we had a solution of 4.0 mL buffer and 1.0 mL Peroxidase for a total solution of 5.0 mL. We then set the spectrophotometer to a value of zero, using a blank containing buffer, H2O2, and Guaiacol Dye. After that, tubes two and three were mixed together and tubes four and five were mixed together for a large solution of with a total of 8.0 mL. Once the two solutions are mixed clean the tube with a Kim Wipe, so all fingerprints are removed. Place the tube with solutions of four and five in the ice bath for twenty minutes. While placing the tube in the spectrophotometer make sure the white strip that is on the tube is facing the direction of the person who is handling placing the tube I the spectrophotometer. Furthermore, just let the spectrophotometer act on the solution for the desired length of time while recording the data at each specific…

    Red Beets Betalains

    Betalains, incandescent tints made using an amino acid called tyrosine, gives beets their vibrant red hue. Plants modify tyrosine by adding other molecules to create other substances, such as morphine in the opium poppies. A tyrosine-making enzyme stays on longer in beets when it is supposed to turn off after a certain amount is made. This is likely the crucial change that beets needed to develop their signature red coloring. At first, there would have been no use for the extra tyrosine. However, at a later stage in their evolutionary history, red beets developed enzymes that made use of the extra tyrosine, creating its red pigment. Research suggests that betalains may help plants weather stress and perhaps attracted pollinators with their…

    The Effcts of Different Wavelengths on Leaf Pigments

    Experiment: First all the materials were gathered. Pigments were separated by chromatography paper. Pigments were loaded in a line on the paper. The paper was folded in a cylinder, stapled, placed in a cylinder with solvent, and sealed with wax paper until the pigments separated. After the pigments separated the paper was taken out to dry and the separated pigments were cut out. Four groups joined together to perform the remainder of the investigation. All of the groups' pigments were separated and put into separate test tubes. Acetone was added. Using forceps, the strips of chromatography paper were "washed" of their pigment. Lastly the absorption spectrum, the absorption pattern for a particular pigment, was measured.…

    Light Color Solutions Intro

    To examine the relationship between color of a solution and the light it absorbs. When it comes down to it our eyes do a accurate job of depicting and distinguishing colors. The purpose of this experiment is to take that a little farther, become more precise. With the use of a spectrophotometer one can determine the wavelength and intensity of the light absorbed. By adding a light source to the solution we can determine the spectrum of that solution, or in other terms the light absorbed. Absorbance is a key part of the experiment, especially the relationship between absorbance and concentration. In other terms, the higher the absorbance, the deeper the color; also the more light absorbed, the less light that passes through. Now when it comes to combining colors, there’s a discrepancy between the color light spectrum, and the painters color spectrum. Since being a child you know that combining two colors would give you one solid color. The same falls true in chemistry, when you combine two chemicals you’ll get the respected outcome, for example, blue and red will make purple. Now in the experiment when you add Erioglaucine and Allura Red, the color emitted is the same as it would be with Crystal Violet. In reality they’re both purple, but when you take closer look at it the color spectrum for Crystal Violet is different then that of the combination to make purple. When you look at the combination of Allura Red and Erioglaucine you see a combination of the red and blue color spectrum. So as far as the color wheel goes, to the eye they’re the same, but when you mix light, you combine the color spectrums, creating a different one than as if it was just the primary color. Beer’s Law shows the relationship for absorbance of a material in which light is passing: A=ebc ( A being absorbance, e being molar absorptivity , b being path of the length of the sample, and c…
