Formal Lab Report Recrystallization Abstract: Test the solubility of the compound of Resorcinol, Anthracene, Benzoic acid, and Sodium salt with different solvents and the Benzoic acid can be recrystallized with all four solvents. Recrystallization technique was performed on an impure sample of Phthalic acid and Naphthalene. The crystals of phthalic acid has 10% recrystallized (mp = 80 –82oC), and the crystals of Naphthalene has 53.3% recrystallized (mp = 210 –

211oC). An unknown sample was recrystallized after determining the best solvent for doing it (toluene). The melting point of the unknown sample (mp = 135 –136oC) indicated that it should be Benzoin. Introduction: The technique of recrystallization is one of the most commonly used methods for purification of solid organic compounds. The basic premise of the technique is reliant on the change in solubility of a solid in a solvent as the solvent cools. Typically, the solid should be soluble in the solvent when it is hot, yet sparingly soluble (or not at all) when in the same
