_ extraction is controlled by partition law.
Correct answer: C. Solvent.
- A. Iodine.
- B. Benzoic acid.
- C. Solvent.
- D. Stationery.
Explanation
Solvent extraction is an equilibrium process controlled by distribution law or partition law. It states that a solute distributes itself between two immiscible liquids in a constant ratio of concentrations irrespective of the amount of solute added. The law is based on experimental evidence.

About Solvent Extraction
Solvent extraction separates a substance by distributing it between two immiscible liquids according to its solubility and partition coefficient. The topic covers selecting suitable solvents, use of a separating funnel, acid-base extraction, phase identification, drying and evaporation, and why several small extractions usually recover more solute than one large extraction.
