Chromatography is used to separate components of mixtures which differ in their rates of?
- diffusion
-
migration
- reaction
- sedimentaion
The correct answer is: B
Explanation
Chromatography is a technique that separates the components of a mixture based on their different rates of migration through a stationary phase and a mobile phase.
- Mobile phase: The moving part of the chromatography setup.
- Stationary phase: The non-moving part of the chromatography setup.
The rate at which a component moves through the chromatography setup depends on how well it absorbs to the stationary phase and how soluble it is in the mobile phase.
