A student rushed through this experiment. Describe the effect that the following procedural changes would have on percent recovery of acetanilide. Briefly explain the basis of each answer. a) Rather than adding 0.5-mL portions of boiling solvent to the acentanilide, the student added 5-mL portions of boiling solvent. b) The student did not pre-heat the gravity filtration apparatus in Part 3. c) The student forgot to cool 5 mL of solvent in Part 5 and washed the crystals with room-temperature solvent.
