Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to

Mario Renteria Mrs. Weathers Chem 04a 27 Jan‚ 2012 Lab Report Introduction: A popular technique in separating components of a mixture is paper chromatography. We use paper chromatography to separate mixtures and isolate there components to collect them individually. In this experiment‚ we will use acid- base indicators to help determine the unknown mixture. Acid- base indicators will change in color when the presence of pHs rise and fall when acids or bases are added to a solution. After setting

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10‚ and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data

United States believe that America has been struck with a "trash crisis"‚ however‚ this is not truly case from the recent Environmental Protection Agency (EPA) facts for 2010. Before‚ we start let us take a moment to discuss what trash or municipal solid waste (MSW) is. MSW is the collection of commonly used items that discarded by the general populace‚ many of these include packaging‚ food scraps‚ grass clippings‚ sofas‚ computers‚ tires and house appliances (EPA). Although the information from the

Exp. 2 Separation of Three Compounds by Extraction Introduction: The purpose of this experiment is do demonstrate the proper procedures of extraction and to develop a practical understanding of this method. In this experiment‚ extraction is used to separate a known acid‚ base‚ and neural compound from each other. The first two compounds undergo proton transfer reactions in the presence of acids or bases. Acids RCOOH‚ like benzoic acid‚ was deprotonated to form RCOO-. Bases RNH2‚ like ethyl 4-aminobenzoate

Municipal Solid Waste Management: Texas ENV/420 Municipal Solid Waste Management: Texas Long-term Costs & Benefit of Course of Action Municipal Solid Waste has a definition all its own. This means more than just trash; but rather what makes up all the bits and pieces of trash and garbage. Society‚ as a whole‚ tends to throw away almost anything that is no longer of value to them. However‚ the plastic‚ cardboard‚ paper‚ books‚ clothing‚ metals‚ foil products‚ and some glass items can be recycled

A Medical Laboratory Technician run test on blood and body fluids to help give doctors answers; answers that can help doctors diagnose what’s wrong with the patient before starting a treatment plan. Throughout these past four years‚ I’ve learned a lot‚ high school has taught me a variety of things‚ but it most importantly has taught me the different type of careers there are. Before I entered high school‚ I didn’t know what a Medical Laboratory Technician was‚ I didn’t even know that was a career;

In order to obtain the data‚ the DataStudio™ software is set up on the computer to use the temperature sensor on the apparatus to collect steadily the temperatures at specified time interval of 5-seconds. After the computer is completely set-up‚ the rest of the apparatus is collected. Water is added to the calorimeter until it is about 2-inches away from being completely full. In order to lower the temperature
