Is separating ink by chromatography a chemical change?
No, separating ink by chromatography is not a chemical change; it is a physical change. In chromatography, the components of the ink are separated based on their different affinities for the stationary and mobile phases without altering their chemical structures. The original substances remain intact and can be recovered after the process.
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?

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.
