In order to dissolve a chemical sample in a recrystallization solvent, add the room-temperature solvent just until it covers the sample in an Erlenmeyer flask on a hot plate.
What is recrystallization solvent?
Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent.
Recrystallization, also known as fractional crystallization, is a procedure for purifying an impure compound in a solvent.
The method of purification is based on the principle that the solubility of most solids increases with increased temperature. Small crystals may trap impurities.
Thus, in order to dissolve a chemical sample in a recrystallization solvent, add the room-temperature solvent just until it covers the sample in an Erlenmeyer flask on a hot plate. Turn on the heat, starting at a low setting and increasing gradually.
