Synthesis of Aspirin and Melting Point Purity Analysis Donald Yeargin CH 222‚ Section 24221 Department of Chemistry Portland Community College Portland‚ OR Abstract The various methods available to synthesize aspirin lead to the need to examine and evaluate production efficiency and purity. The purpose of our experiment was to synthesize acetyl salicylic acid (aspirin) and then determine the relative purity of the synthesized sample by observing the melting point temperature range. The procedure

making the bacteria take on various phenotypic characteristics. Background Information: Genetic transformation is one of the most important processes in biotechnology. Essentially‚ genetic transformation involves the process where a cell (in this lab‚ a bacterial cell) takes up foreign DNA from its surroundings and incorporates it into its own DNA. This gene transfer is accomplished with the aid of a plasmid‚ a

There are many branches of food science‚ all of which study different aspects of food such as safety‚ microbiology‚ preservation‚ chemistry‚ engineering‚ physics and the like. Until the advent of molecular gastronomy‚ there was no formal scientific discipline dedicated to studying the processes in regular cooking as done in the home or in a restaurant. The aforementioned have mostly been concerned with industrial food production and while the disciplines may overlap with each other to varying degrees

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average

Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride‚ was used as the pure organic compound. Crude acetanilide underwent crystallization process using the preferred recrystallizing solvent‚ water. The crystallization process was when crude acetanilide was placed in hot water bath and was cooled after in an ice bath which would then yield to the formation of crystals of pure acetanilide. The percentage
