Which of the following methods is the most common method for separation of liquid components from a mixture?
Correct answer: D. Distillation
- A. Dialysis
- B. Solvent extraction
- C. Chromatography
- D. Distillation
Explanation
Distillation is a widely used and effective method for separating components of a liquid mixture based on differences in their boiling points. The component with the lower boiling point vaporizes first and is then condensed and collected separately.

About Analytical Chemistry
Analytical chemistry identifies and measures substances using separation and instrumental methods. Chromatography is studied through stationary and mobile phases, retention and Rf values, while spectroscopy connects absorption of electromagnetic radiation with molecular structure and supports qualitative and quantitative analysis through techniques such as UV-visible and infrared spectroscopy.
