    Determining the Concentrations of Red Dye in Sodas Abstract The use of red dye #40 is common in various soft drinks today. The labels on these beverages do not specify how much dye we are consuming. We did this experiment to find out which soda uses the most dye. Using a spectrophotometer‚ we measured how much light is absorbed by various known concentrations of red dye. After collecting this data‚ a standard curve was made that correlated the concentration of red dye #40 to its absorbance rate. Our

    Separations: Chromatography of M&M and Ink Dyes Almost all substances we come into contact with on a daily basis are impure; that is‚ they are mixtures. Similarly‚ compounds synthesized in the chemical laboratory are rarely produced pure. As a result‚ a major focus of research in chemistry is designing methods of separating and identifying components of mixtures. Many separation methods rely on physical differences between the components of a mixture. For example‚ filtration takes advantage of substances

    demonstrated that the color of a given food dye depended on which light was transmitted in the visible spectrum and which light was absorbed. A quantitative measurement of the absorbance spectrum of each food dye was obtained through spectrophotometry.1 Through this method‚ we determined that the wavelength of maximum absorbance of a given food dye was directly correlated to the color of that food dye. Further‚ darker food dyes absorbed more light than lighter food dyes (Table 1). The relationship between

    Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

    Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

    this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy.  This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement.  Diffusion is the passive movement of molecules from an area of higher concentration

    the ideas of cultural diffusion. Cultural diffusion is the exchanging and adaptation of ideas amongst people of the world. It is a constant force that allows us to accept and modify an idea to mold into our own world. Throughout great civilizations of history‚ the idea of cultural diffusion has spread and continues to spread in present time. This idea usually enforces contact between neighboring strangers. McNeill addresses the specific issue of how cultural diffusion came to shape new civilizations

    Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue

    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
