You purify two colorless solids (2 and 3) by recrystallization. Both have a melting point range of 102-104 C. You forgot to label your work, so you are not sure which solid is 2 and which is 3. You have a small amount of an authentic sample of pure 2 available in your lab. How can you identify the unknowns?
