Chromatography is a physical process used to separate the components of a mixture based on their different interactions with a stationary phase and a mobile phase. While the components may physically move or separate during chromatography, the chemical composition of the substances remains unchanged, making it a physical change.
Chromatography is simply a process used for separating chemicals that were mixed together, into different locations (on a strip of paper, or other absorbent material) hence, it is a physical change, not a chemical change.
Because dyes that were once combined together in a homogeneous mixture were simple separated, without and chemical reactions.
Separating compounds using chromatography is a physical change.

Why chromatography is a physical process?
Chromatography is physical techniques for separation. The method involves the dissolution of the materials in a mobile phase, then forced through a stationary phase in which the components of the sample separate.
What causes the reaction in chromatography?
In chromatography, the reaction is caused by the interaction between the molecules of the sample being separated and the stationary phase (such as paper or silica gel). This interaction leads to different components of the sample moving at different rates, resulting in separation based on their affinity for the stationary phase.
How do you change from reversed phase chromatography to normal phase chromatography?
To change from reversed phase chromatography to normal phase chromatography, you will need to switch the stationary phase from non-polar (reversed phase) to polar (normal phase). You may also need to adjust the mobile phase composition and elution conditions to suit the new separation mechanism. Additionally, consider if changes in detector and column specifications are necessary for optimal performance in normal phase chromatography.

What kind of change is needed to separate a mixture into its components?
A physical change is needed to separate a mixture into its components. This can be achieved through processes like filtration, distillation, chromatography, or evaporation, which rely on the differences in physical properties between the components of the mixture.
Is crumple a chemical change or physical change?
Crumple is a physical change.
