different concentrations of alcohol to extract red and blue dyes‚ and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography‚ resolution and selectivity played major roles in making the experiment work. The experiment demonstrated a common use of chromatography‚ and works to explain a way to separate mixtures. The dyes were successfully separated and analyzed in the cartridge.

compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions‚ one of which is with the reaction with nitrous acid producing an azo dye. In this study‚ the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes‚ oils and in some food ingredients specifically curry and chilli powder. Furthermore‚ this study aimed to understand the mechanism behind the synthesis of 1-phenylazo-2-naphtol

What is American Federalism? According to Dye (2011)‚ "nations are not truly federal unless both national and subnational governments exercise separate and autonomous authority‚ both elect their own officials‚ and both tax their own citizens for the provision of public services" (p.263). American Federalism is just that. In the United States each state has their own government with elected officials‚ to go even further each town within these states also have their own elected officials. These officials

liter sample is dispensed into well by holding the tip of the micropipette just inside the well so as not to puncture the bottom. 7. We continued inserting the remaining dye samples into each of the remaining wells‚ using the same amounts for each well. For example: Well #2 contains Dye sample #2 and Well #3 contains Dye sample#3 and so on. 8. After we loaded the E-Gel‚ we started the 35-minute electrophoresis run. This was confirmed by a steady green light. 9. The current automatically

Ashley Spees CHM 261- Batzer Chem Final Write Up- Kool Aid Lab Total Acid This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish‚ though‚ due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint. Blue stock solution: 3 mg/L

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

CHAPTER ONE 1.0 Introduction At the heart of transforming raw ingredients into food for human consumption is the mixing operation. It’s a main task which other food processing steps also share to establish consistency. Whether a food product requires small-scale mixing by hand or high volume blending of multiple ingredients‚ home cooks and food process engineers alike know the importance of proper mixing. Even with the right amount of ingredients and flavors‚ a great recipe will not transform

Tie-Dye Grignard Synthesis Abstract: 4-Bromo-N‚N-dimethylaniline underwent a Grignard reaction with diethyl carbonate to produce a type of the tie-dye chemical triarylmethane. This specific triarylmethane produces a vivid crystal violet color when dyed. The experiment was first heated under reflux to produce the necessary Grignard reagent as a grey liquid. It was then reacted with diethyl carbonate and hydrochloric acid to produce crystal violet. The resulting chemical was very absorbent to
