Differential Extraction
Mediumchemistry
Differential extraction of organic compound from aqueous solution uses an organic solvent that is:
Select the correct option:
Solution
Incorrect! Answer:
Immiscible with water and selective dissolving solute
- Goal: To extract an organic compound that is present in an aqueous (water) solution.
- Reagent Selection: A solvent is added that is immiscible with water (e.g., Ether, Chloroform).
- Partition Principle: The organic compound should be significantly more soluble in the organic solvent than in water.
- Process: The aqueous solution and the organic solvent are shaken in a separating funnel. The compound 'partitions' itself between the two layers.
- Efficiency: Performing multiple extractions with smaller volumes of solvent is more efficient than a single extraction with a large volume.
- Separation: The two layers (aqueous and organic) are then separated due to density differences.
