A student who was isolating aspirin stopped the experiment after filtration step alumina. One week later, the methanol was evaporated and the experiment was completed. The melting point of the aspirin was found to be 110-115 degrees C. Explain why the melting point was low and why the melting point was so wide.
thanks in advance
A range of more than about 1-2 degrees plus the melting point being lowers means there is one or more impurities in the final product.
