2) Dissolve impure solid
• weigh out crude solid and record its mass (also take a melting point for reference)
• add a boiling chip or boiling stick (otherwise, it may "bump" and spill)
• use a minimum amount of hot solvent (Add a bit, heat/swirl. Not dissolved? Add more!)
NOTE: IF YOU USE TOO MUCH SOLVENT, YOU WILL GET NO CRYSTALS!
