Chemistry

Asprin(acteyl salicylic acid) can be synthesized by reacting acetic anhydride with salicylic acid. Assume the reaction was run and 1.75 grams of a solid product was obtained. Recrystalization of the 1.75 g mixture yielded 1.50 g of asprin.

a. What was the percentage recovery of asprin from the recrystalization?

b. Why was recrystalization used for the purification of asprin rather than filteration or evaporation? Explain your answer.

  1. a)% recovery = [final mass/ initial mass] x 100%

    b) hint: think about the state of matter of the impurities
