Recrystallization of Acetanilide: Prelab 1. What is the purpose of recrystallization? Name:_ 2. To purify a compound by recrystallization, one must choose a solvent which will dissolve the compound of interest when when but which will not dissolve the compound appreciably 3. What will happen if the recrystallization mixture is cooled very quickly so that crystals form very rapidly? 113 4. In this experiment you will recrystallize acetanilide. Give a fact or two about this compound. 5. A liter of water at 95 °C will dissolve 85 grams of "Compound X. At room temperature (-25°C), a liter of water will dissolve only 2 grams of Compound X. A. If 38 grams of Compound X is added to a liter of water at 95°C, will it all dissolve? B. If 38 grams of Compound X is added to a liter of water at room temperature, will it all dissolve? PRELAB CONTINUED ON NEXT PAGE If not, how much will remain undissolved? C. If 38 grams of Compound X is dissolved in a liter of water at 95°C and then cooled to room temperature, how much will remain dissolved in the water?
