Crystallization procedure
WebMar 29, 1999 · Crystallize the solute. This involves allowing the hot solution with the solute dissolved to return to room temperature slowly. The slower the cooling process, the less chance of trapping impurities in the developing crystal lattice. Allow the solution to reach room temperature. WebRinse the crystals on the Büchner funnel with a small amount of fresh, cold solvent (the same solvent used for recrystallization) to remove any impurities that may be sticking to the crystals. To dry the crystals, leave them in the filter funnel and draw air through them for several minutes.
