Which of the following is a method used to separate different compounds in a mixture using a solvent?

• A. Electrolysis
• B. Centrifugation
• C. Distillation
• D. Paper chromatography

Answer: (D)

Verified step by step guidance

1. Understand that the problem asks for a method used to separate different compounds in a mixture using a solvent.
2. Review each option and identify whether it involves a solvent and separation of compounds based on their chemical properties:
3. Electrolysis involves using electrical current to cause a chemical change, not separation by solvent.
4. Centrifugation separates components based on density by spinning, without using a solvent to separate compounds chemically.
5. Distillation separates components based on differences in boiling points, involving phase changes but not specifically using a solvent to separate compounds chemically.
6. Paper chromatography is a technique where a solvent moves through a paper, carrying different compounds at different rates, effectively separating them based on their affinity to the solvent and paper.
