BROMINATION OF ACETANILIDE OBJECTIVE Aim of the experiment was too brominate acetaldehyde to form p-bromoacetanilide. INTRODUCTION Acetanilide is a chemical compound with the chemical formula of C6H5NH(COCH3). It is a crystalline solid that is prepared by acetylation of analine and is widely used in the dye industry. This crystalline solid is an odourless solid chemical that has a flake or leaf like appearance. It is also known as N phenylacetamide‚ acetanil or acetanilide. Its former

instrument of learning a quantitative method of analysis‚ i.e.‚ of the gravimetric analysis. This type of analysis‚ which makes use of the weight of the samples was used for the experiment and required the precipitation of our analyte‚ SO4-2‚ and its filtration as a BaSO4 precipitate so as for weighing it. The weight of the SO4-2 was determined through the data gathered in the experiment‚ particularly from finding the weight of the BaSO4 precipitate. This was taken into the proportion of the weight sample

concentration of salts to an area of greater concentration (Campbell). To maintain the proper balance of salts and water in the aquatic environment fish‚ and all vertebrates‚ evolved to utilize a very specialized organ to solve this problem: The Glomerular/ Vertebrate Kidney (Washinton). In early evolving species‚ fish were beginning to live in freshwater systems after entire millennia of living in the oceans (Washington). This meant that their cells had a higher concentration of salts than the environment

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

Introduction: This is a two week experiment involving transformation of matter where we will investigate the synthesis of the dye indigo‚ which will be made‚ isolated by the process of vacuum filtration and then evaluated. Indigo is the name given to an organic molecule with an intense blue color. It has been used to dye cotton and wool fabric‚ it is commonly known as the source of the color in blue jeans.
