1. Calculate the theoretical yield of aspirin in grams from the salicylic acid below.
Given Mass of salicylic acid: 2.00 g
Theoretical yield of aspirin (g): _______________
2. Calculate the percent yield of aspirin
Given Mass of watch glass + aspirin: 44.47 g
Given Mass of empty watch glass: 44.30 g
Mass of aspirin (g): _______________
3. Calculate the percent yield of aspirin.
Percent yield: _______________
Given: Mass of salicylic acid: 2.00g
Mass of watch glass (empty): 44.30g
Mass of watch glass + aspirin: 44.47g
ph in test tube 1: 2
ph in test tube 2: 3
ph in test tube 3: 3
ph in test tube 4: 3
4. Based on the given data above, summarize the pH test results and draw comparisons between the four solutions.
5. Based on the given data above, summarize the ferric chloride test results and draw comparisons between the solutions.
6. Do the results indicate the commercial aspirin was pure? Was the acetylsalicylic acid pure? Was the synthesized aspirin sample pure? Explain.
