Aspirin can be made in the laboratory by reacting acetic anhydride (C₄H₆O₃) with salicylic acid (C₇H₆O₃) to form aspirin (C₉H₈O₄) and acetic acid (C₂H₄O₂). The balanced equation is
In a laboratory synthesis, a student begins with 3.00 mL of acetic anhydride (density=1.08g/ml) and 1.24 g of salicylic acid. Once the reaction is complete, the student collects 1.24 g of aspirin.
