Unformatted text preview: Aspirin Feb 13, 2008 Section 2731/2712 Chemistry 002 Ruili Nick Hookham Purpose- The purpose of this lab was to synthesize and analyze a compound made from simple and readily available materials. As well as during the analysis to determine the purity of the compound. Procedure- First, weigh about 2g of Salicylic acid and add 4mL of acetic anhydride and 5 drops of sulfuric acid. Place test tube containing mixture into a hot water bath. After reaction is complete, remove test tube and pour contents into a water and ice mixture. Filter out the precipitate using an aspirator with filter paper. Then test the product against pure aspirin and pure salicylic acid using FeCl 3 . Then titrate your NaOH sample to determine its molarity.
