1. Does purified aspirin appear to be purer than crude aspirin? What is your evidence?

2. Impurities tend to lower the melting-point temperature of a solid and make it melt over a range of temperatures rather than at one sharp temperature. The published melting point temperatures are 159 degrees C for salicylic acid and 135 degrees C for aspirin. Discuss your melting point data compared to theses standards values.

My salcicylic acid melting completed at 121.3 degrees C. and the purified aspirin melting completed at 124.1 degrees C.
