This ensuresChem 105 Onlinethat all the spectator ions are rinsed off the filter paper and precipitate and notrecrystallize-which would add an additional mass on the filter paper when dried.7. Carefully remove the filter paper (it will still be very moist) and place it on a paper towelto dry overnight.a. If you are cramped for time, an oven will work set at 200-225°F. Set the wet filterpaper on a baking sheet and place in the oven. Check it regularly to not burnthe filter paper.b. A sunny window is a happy medium for wet filter paper as well. Ⓒ8. Repeat the process one more time for a second trial.
