How is the melting of an impure compound expected to change with recrystallization?
The melting point of an impure compound will become closer to that of the actual melting point of the pure substance with recrystallization of your mixture.
What property of a particular solute towards a solvent is necessary for recrystallization to occur?
The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.
