Which of the following analytical technique is used for separating similar substances by preferential adsorption or partition between two phases?
Correct answer: D. Chromatography
- A. Distillation
- B. Dialysis
- C. Solvent extraction
- D. Chromatography
Explanation
Chromatography is a powerful separation technique where components of a mixture are separated based on their differential distribution between a stationary phase and a mobile phase. This distribution is governed by processes like adsorption and partition.

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.
