In which of the following scenarios might you expect the observed melting point to be depressed? Choose all that apply. a. The heating rate for measuring the melting point was set too high. b. The percent recovery of recrystallized solid was less than 100%. c. A solid that was recrystallized from hexane was filtered and dried without washing with additional hexane while it was on the filter funnel. d. A solid recrystallized from toluene was left on the filter funnel for only a short time before its melting point was measured. e. The melting point capillary tube was packed with too much material.
