Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

Caffeine in the diet Email this page to a friend Bookmark & Share Printer-friendly version Caffeine is a substance that is found in certain plants. It can also be man-made (produced synthetically) and then added to food products. It is a central nervous system stimulant and a diuretic (substance that helps rid your body of fluids). Function Caffeine is absorbed and passes quickly into the brain. It does not collect in the bloodstream or get stored in the body. It leaves the body in

Laboratory #16: Analysis of Grease in Water by Solvent Extraction Experiment Date: 2/19/10 Due Date: 2/26/10 II. Objective The goal of this lab was to determine the amount of impurity‚ in the form of oil‚ in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

Evidence Homework #1 Topic: Caffeine Preview: Every morning when I wake up the first thing I do after brushing my teeth is walk straight to the coffee pot. I pour myself a hot rich cup of coffee to start the day off. On my way out the door I grab my go cup and fill it up. When I finally get to school I get myself another cup of coffee. How many miller grams of caffeine do you think I have drank at this point? According to the Mayo Clinic a healthy amount of caffeine for an adult is 200 to 300 miller

EXTRACTION Organic Chemistry Laboratory This experiment was conducted in order to compare single and multiple extraction of caffeine from dried tea leaves and to calculate the percentage yield of caffeine for both extraction procedures. The group was assigned to do the multiple extraction. Before the extraction proper‚ the water bath containing the anhydrous sodium carbonate and distilled water was heated. As the sodium carbonate dissolves‚ tea leaves were added in the mixture and allowed to

the four different pigments types of a leaf. As the filter paper with the solvent will separate the pigments in terms of solubility‚ a clear segmentation of each is expected to show off. As various chemicals were used in the whole process of this lab‚ certain variables might have influenced the results in terms of the purity of each chemical or purity of the used filtrate. Background The chloroplast‚ basically‚ is the organelle responsible for photosynthesis. Structurally it is very similar to
