The literature melting point of acetylsalicylic acid is 134-136 °C (Sigma-Aldrich SDS, 02/28/2015) and the melting point range of the recrystallized product is 124.5-125.2 °C. Is the recrystallized acetylsalicylic acid pure? A. The compound is pure because it has been recrystallized. B. The compound is pure because it has a lower melting point than the literature value. C. It is impossible to know if the compound is pure or impure. D. The compound is impure because it has a lower melting point than the literature value. E. The compound is pure because it has a narrow melting point range.
