The process of extracting crude from a liquid sample by repeatedly mixing it with fresh portions of an immiscible solvent is called?
Everyday Science / Chemistry — Multiple-choice practice
- A. Multiple batch extraction
- B. Precipitation
- C. None of these
- D. Fractional distillation
Correct answer
Multiple batch extraction
Explanation
Explanation A single extraction may not remove all solute. Repeated extraction with f resh solvent portions improves yield. The process is done until maximum solute transfer occurs. Also called repeated liquid-liquid extraction . Different from fractional distillation (separates liquids by boiling points) and precipitation. Last updated question 25 feb 2026
