Please help with finding theoretical yield in trial 1 & 2.
also n Chem 105 Online recrystallize-which would add an additional mass on the filter paper when dried. that all the spectator ions are rinsed off the filter paper and precipitate and not Carefully remove the filter paper (it will still be very moist) and place it on a paper towel to dry overnight. a. If you are cramped for time, an oven will work set at 200-225°F. Set the wet filter paper on a baking sheet and place in the oven. Check it regularly to not burn the 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.
