The solubility of salicylic acid in diethyl ether is 1 g/3 mL at 25 C. Is diethyl ether an appropriate solvent to use for recrystallizing salicylic acid? Explain.

No, it is not an appropriate solvent for recrystallizing salicylic acid. First, the salicylic acid is too soluble in diethyl ether at room temperature. Second, in order to obtain a hot saturated solution, one would have to heat the mixture and, because the boiling point of diethyl ether is low (bp = 35 C), evaporation of the solvent would be a problem. Furthermore, diethyl ether is a flammable solvent and a well-known inhalation anesthetic and should not be used for recrystallizations.
