First we set up the Buchner funnel and wet the filter paper to ensure good suction.
We then poured the aspirin solution into the funnel. The flask was rinsed with water and poured into the funnel to make sure no crystals were left behind. Then we dried the crystals by pulling air through the funnel for 15 minutes.
Once the excess water was removed, we removed the filter paper with the aspirin on it with tweezers and place it on a watch glass. We moved the aspirin onto a double folded paper towel and placed this on a side table to completely dry over fall break.
