Solution
Correct Answer:
Layer where it is more soluble
Differential Extraction is a technique to separate a compound from its solution in an aqueous solvent by shaking it with an immiscible organic solvent.
- Partition Law: The compound distributes itself between the two solvents according to its solubility in each. At equilibrium, the ratio of concentrations (K=Corganic/Caqueous) is constant.
- Success: Multiple extractions with smaller volumes of solvent are more efficient than a single extraction with a large volume of solvent. The organic layer containing the compound is luego separated using a separating funnel.
This easy difficulty chemistry question is from the chapter purification and characterisation of organic compounds, covering the topic of differential extraction. It appeared in the 2025 exam.
