Acetic acid will be most economically separated from a dilute solution of acetic acid in water by____________________?
Correct answer: D. Solvent extraction
- A. Absorption
- B. Continuous distillation
- C. Evaporation
- D. Solvent extraction
Explanation
Acetic acid is present in dilute aqueous solution, and distilling it from water is relatively energy-intensive because of their volatility relationship. Liquid-liquid solvent extraction can selectively remove the acid more economically.
