Simple Distillation‚ Gas Chromatography: Preparation of Synthetic Banana Oil Introduction This experiment gave us the opportunity to work with a variety of new procedures as well as practice procedures that are new to us within the past few weeks of labs. Within the context of the scenario‚ we find that a distilling company that markets a popular banana liqueur is having problems. The banana plantation that they use to create their banana extract was hit hard by a hurricane and their reserves

Chemistry 266 Dominick Armstrong 10/10/2012 Acid-Base Titration Introduction Acid and bases are two important classes of compounds that react to form a salt and water. When mixing acids and bases a precise amount of the base must be added in order to reach the equivalence point. At this point‚ one reactant has been exactly consumed by the addition of the other reactant. When performing chemical reactions chemist use a process called titration to determine the equivalence point of the

Is Higher Education Worth the Price? The question of whether or not higher education is actually “worth it” is an entirely subjective on. To objectively determine if higher education will give a high return on investment‚ one needs to first understand what they are hoping to gain out of the entire experience. Higher education does worth the price because it helps students to build their self-fulfillment‚ provide more monetary opportunities and reach their final goal . In the United States‚ for

Extraction Important Peaks Concluded Compound C-5 #1 -CH‚ C=O cyclopentanone C-5 #2 -OH‚ -CH 1-hexanol D-4 #1‚2 C=O‚ -CH Cannot conclude Preparative Gas Chromatography was used to separate volatile compounds‚ which can then be identified. The injected sample becomes vaporized and was carried through the mobile column. It is usually carried by an inert gas. The gases were moved through the stationary column. The polarity of the components to the column would cause the separation of the components

Drugs screen using Thin Layer Chromatography of basic illicit drugs Abstract The majority of evidence submitted to crime labs comes from drug-related crimes. Often‚ this evidence includes unidentified powders that may be illegal drugs. In order to prosecute individuals for possession of illegal substances‚ it is necessary for forensic scientists to positively identify any suspected drugs submitted to the laboratory. In addition‚ forensic toxicologists must determine the identity
