When might repeated crystallization become necessary for the purification of compounds?

Options

  1. AWhen the compound has a low solubility in the solvent
  2. BWhen the compound is highly soluble in one solvent and very little soluble in another solvent
  3. CWhen the compound has a high melting point
  4. DWhen the compound is in a gaseous state

Correct answer

B. When the compound is highly soluble in one solvent and very little soluble in another solvent

Step-by-step solution
