The reverse process of fractional crystallisation is called__________________?
Correct answer: B. Leaching
- A. Stripping
- B. Leaching
- C. Differential distillation
- D. Absorption
Explanation
Leaching transfers a soluble component from a solid into a liquid solvent, making it the reverse-direction counterpart of crystallising a dissolved component into a solid phase. Stripping and absorption are gas-liquid operations, not solid-liquid crystallisation counterparts.
