ASPRIN synthesis expirament:

What is the purpose of the

concentrated sulfuric acid used in the first step?

2. What would happen if the sulfuric acid was left out?
3. If you used 5.000 g of salicylic acid and excess acetic anhydride in the

preceding synthesis of aspirin, what would be the theoretical yield of

acetylsalicylic acid in moles? In grams?
4. Most aspirin tablets contain five grains of acetylsalicylic acid. How many

milligrams is this? 1 grain = 0.0648 g
5. If the aspirin crystals were not completely dried before the melting point

was determined, what effect would this have on the observed melting polnt?

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 C4H6O3+C7H6O3→C9H8O4+C2H4O2 In a laboratory synthesis, a student begins with 2.80 mL of acetic anhydride (density=1.08g/ml) and 1.24 g of salicylic acid. Once the reaction is complete, the student collects 1.21 g of aspirin. Part A) Determine the limiting reactant for the reaction. acetic anhydride or salicylic acid Part B) Determine the theoretical...
