Given the balanced reaction between salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) to produce ASA or acetylsalicylic acid (C9H8O4) and acetic acid (C2H4O2), the following experimental materials are provided: 5.00 g of pure salicylic acid, 7.14 g of acetic anhydride and 8 drops concentrated sulfuric acid as catalyst. After successful synthesis, the group was able to collect 5.25 grams of acetylsalicylic acid. (Atomic weight: C = 12 amu; H = 1 amu; O = 16 amu; density acetic anhydride = 1.08 g/mL).
