Question

1. What is the theoretical yield of aspirin in your synthesis? The mole ratio is 1:1 between salicylic acid and aspirin in this reaction. 2. The melting temperature of pure acetylsalicylic acid is 135° C. Based on the results of the melting temperature test do you believe that your aspirin sample is pure? Explain. 3. Based on the results of the absorbance testing with the spectrophotometer, what is the percent purity of your sample of aspirin? Does this percent purity compare well with the results of the melting temperature test? Explain. 4. Use your percent purity calculations to determine the percent yield of your synthesis of aspirin.
