The solvent used in liquid-liquid extraction should have _______________ less than one?
Correct answer: D. Neither A. nor B.
- A. Selectivity
- B. Distribution co-efficient
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
A useful extraction solvent should have high selectivity and a favourable distribution coefficient, not values below one. Therefore, neither property is required to be less than one.
