Repeated extraction using portion of solvent are more?
- Accurate
- Efficient
- Slow
- Rapid
Explanation
Repeated extraction using portions of solvent is more efficient than using a single large portion of solvent.
Efficiency in repeated extractions:
When you use small portions of solvent repeatedly, each extraction removes a portion of the solute from the original solution, maintaining a higher concentration gradient for subsequent extractions.
This leads to a more efficient transfer of the solute to the solvent.
Concentration gradient:
By repeatedly adding fresh solvent, you create a higher concentration difference between the solute in the original solution and the solvent, allowing for better transfer of the solute.
Single extraction limitation:
Using a single large volume of solvent may not be as efficient because the solute may not have enough time to fully transfer to the solvent due to a lower concentration gradient.
