Discussion: In this experiment we added salicylic acid to 2.0 ml acetic anhydride for the molecules to react to produce aspirin. The 85% concentrated phosphoric acid was added to act as an acid catalyst to lower the required activation energy for the reaction. We then allowed the reaction to stand for about 10 minutes to allow the phosphoric acid to spread through the solution. We than heated the solution to add energy to the system to obtain the activation energy needed for the reaction. After heating the solution, letting the solution chill allowed the aspirin to crystalize into a solid. Vacuum filtration was use to isolate only aspirin on to the filter paper to be weighed to record the mass of aspirin produced. The observed percent yield
