Question

Quizplus · Accepted Answer

Recrystallization is the best technique for purifying solid substances. It involves dissolving the solid in a suitable solvent and then slowly cooling the solution to precipitate pure crystals. Any impurities will remain in the solvent and can be removed through filtration. Dilution, dissolution, boiling, and melting may not effectively remove impurities from a solid.
