Look up the accepted melting point for aspirin (acetylsalicylic acid) in either the Merck Index or the CRC or the internet. Prepare a very small table with this accepted melting point (use a citation to show where you got the value), your experimental melting range for crude aspirin, and your experimental melting point range for recrystallized aspirin. Consider what this data says about the purity of an aspirin sample. Why do you think may cause discrepancy between an experimental sample of aspirin and a recrystallized version? How would that show up in the melting point of Aspirin?
