Remove the liquid from the crystals by filtering under suction in a Büchner funnel. Wash the crystals with two 10-mL portions of cold water to remove any excess reagents. Continue suction through the crystals for several minutes to help dry them. You will perform some tests on this crude product today, and your instructor may ask you to save a small portion of your crystals for a melting point determination to be performed during the next laboratory period. If your instructor directs, set aside a small portion of your crystals in a beaker to dry until the next lab period.
