2) (4) Successful recrystallizations involve several steps, each which must be carried out correctly. For the setups mentioned below identify whether the technique is correct lab procedure. If so, briefly explain why. If not, what is the correct procedure? a. Solute to be recrystallized is dissolved in liberal amounts of hot solvent and placed immediately into an ice bath to crystallize. b. Some black particles remain in the solution despite the addition of more hot solvent, so the solution is put through a hot gravity filtration, cooled and vacuum filtered.
