Chromatography is used to separate components of mixture which differ in their rates of ?

Chromatography is used to separate components of a mixture based on their migration or movement through a stationary phase, such as a solid or a liquid, and a mobile phase, such as a gas or a liquid. The components in the mixture have different rates of migration, so they will separate as they move through the stationary phase, allowing us to identify and isolate each component. This is because each component has a unique combination of physical and chemical properties that affect how it moves through the stationary phase and the mobile phase. The process of chromatography can be compared to a race, where the components in the mixture are like runners and the stationary and mobile phases are like a track. Just like runners move at different speeds on a track, the components in the mixture will move at different rates through the stationary and mobile phases, leading to separation.
