ry the crystals by pulling air through after vacuum filtration (to help them dry). O Keep the crystals open to the air for quite a while during the drying step. O Precipitate the crystals as fast as possible. O Rinse the crystals on the filter with a small amount of the ice-cold solvent. O Use a very small amount of ice-cold solvent and a spatula to remove any crystals left in the flas

Answer:

C. Precipitate the crystals as fast as possible

Explanation:

C. Precipitate the crystals as fast as possible

Precipitation if done fast , can lead to the formation of impure crystals , as impurities also get stuck inside the crystals. So it must be done slowly to obtain the pure crystals . Slower the crystals form , purer they are .

All the other options can lead to a successful recrystallization.
