    Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total yield of 1.757g of purified aspirin‚ which had a melting point range of 125°C-130°C. Results of the Ferric Chloride test

    Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected
