In liquid extraction, if the selectivity is unity, then___________________?
Correct answer: C. No separation will occur
- A. Separation of the constituents is the most effective
- B. Amount of solvent required will be minimum
- C. No separation will occur
- D. Solvent flow rate should be very low
Explanation
Selectivity measures how preferentially the solvent extracts one solute over another. A selectivity of unity means both constituents are extracted equally, so no separation is achieved.
