Procedure Include a step-by-step procedure for what you did in the lab‚ written in your own words. Data and Observations * List your original predictions about the expected pigment components of each candy color. * Create an organized and labeled data table that lists the color and distance traveled of each pigment separated from each original candy color or ink type. Remember to have two separate sections or tables for the two solutions (salt water and alcohol) used. * Also include any

Supply Chain Management- Paint Industry By: Purvi Mehta Abstract The purpose of this paper is to outline the importance and benefits‚ paint industry can achieve through supply chain integration. These benefits are primarily in the area of achieving superior customer service and operating with lower working capital. A three level framework for achieving the integration has been proposed which is in the form of structural integration‚ process integration and performance integration. The paper also

Hand prints Handprints are marks that are produced after the hand has been in contact with pigments and the marks were usually left on rocks or walls. This can be trace way back to the Paleolithic people. Different purposes have been proposed by different theories about the essence of the handprints‚ among them being that they were used to mark as signatures for artists‚ showing territories for clans or families‚ showing status among society members‚ symbolizing sexual rituals (Nash‚ G 2012)‚ just

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 solubility. The more soluble the pigments are the faster they will move through the paper. Paper chromatography is most commonly used to separate pigments‚ dyes and inks. In forensics‚ paper chromatography

Paper chromatography is used to break down colors with using water and the way the colors separate. 2. Doctors can use it to test for alcohol in people’s blood. People can also use it to check for pollutants in the water. Pharmacists can use it to find out how much of each chemical is in each product. 3. I searched

spectrum and the differences of the different pigments. Percentage transmittance in Table 1 show that the lower the number‚ the more dense that solution is at that specific wavelength. As the numbers get higher‚ the less dense it is and if the number is 100 at a specific wavelength then the solution was clear. As we can see from Table 1‚ each of the pigments had different low transmittance based on how high the absorption was in each of the pigments. For this we calculated that at there was a peak

leftover blueberries * Baking soda * Vinegar * Corn syrup * Corn starch * Procedure Each plant was finely chopped and ground and individually boiled in water. Once the water was evidently stained with the pigment of the plant used‚ the heat source was put off and the contents of the pot were left to cool. When cooled‚ the residues were strained and the resulting dye was collected in a container and was set aside. This process was done three times‚ for

When a beetroot cell is exposed to various kinds of temperatures‚ its plasma membrane is affected and may change in structure resulting in the leaking of betacyanin. If the temperature changes‚ then I would expect to observe that there would be a change in the concentration of betacyanin that has leaked from a beetroot cell. In specific‚ at high temperatures‚ the phospholipids that make up the plasma membrane of the beet root cell become progressively more destabilized causing them to transform into
