Recrystallization

Recrystallization is a technique for purifying solids by dissolving them in a solvent at high temperatures and then cooling to form purer crystals. The process involves selecting a solvent where the solid is insoluble at room temperature but soluble at high temperatures. After dissolution, cooling allows pure crystals to form, leaving impurities in solution. Seeding can aid crystallization. The final product's purity is tested by melting point analysis. The key is choosing the right solvent and understanding the solubility of impurities.
