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

The purpose of this lab was to synthesize indigo and an azo dye and to determine how effective each dye was to dye different types of fabrics. 0.168g of 2-nitrobenzaldehyde was dissolved into acetone along with 25 drops of distilled water and NaOH to synthesize indigo. The solution was filtered‚ and the solid indigo was placed into the filter flask to reduce indigo to leucoindigo with 10mL of 3M NaOH. The flask was heated along with sodium dithionite and distilled water added to the flask. Afiber

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 uncolored drinks

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.
