Recrystallization - PowerPoint PPT Presentation


Recrystallization for Solid Organic Compound Purification

Recrystallization is a laboratory technique used to purify solids based on their different solubilities. It involves dissolving an impure solid in a suitable solvent, cooling the solution to allow pure crystals to form, filtering to isolate the purified solid, and drying it. Finding a good recrystal
