Which Synthesis Code gives the highest percent yield? 2. Which Synthesis Code gives a high purity aspirin? 3. Based on your answer in analysis question 1, how many percent excess acetic anhydride will you use in Part Ill? Part II Limiting and Excess Reactants Concent Application

Answer 1

solution Purpose of determining melting point of aspirin during experiment is to determine purity of it. of melting point leange is closer (f smaller) to melting point then asploun is more purer
