MCQ
Which techniques is based on the difference in the solubilities of the compound and the impurities in a suitable solvent?
- ASublimation.
- ✓Crystallisation.
- CDistillation.
- DNone of these.
✓
Answer
Correct option: B.
Crystallisation.
Crystallisation process is based on the difference in the solubilities of the compound and the impurities in a suitable solvent. The impure compound is dissolved in a solvent in which it is sparingly soluble at room temperature but appreciably soluble at higher temperature.
