Calculate theoretical and percent yield. In this experiment, salicylic acid and acetic anhydride will be reacted to form acetylsalicylic acid in an acid catalyzed reaction. In a reaction tube, add approx. 140 mg salicylic acid, a boiling chip and a small drop of 85% phosphoric acid. Add 0.3mL acetic anhydride, which should wash the reactants to the bottom of the tube. Mix thoroughly. Heat in a beaker of water at 90oC for 5 min. Cautiously add 0.2 mL water to...
