Chromatography is a physical change because even though you are separating colors the original atomic identity of the colored ink being separated is still retained showing that a chemical reaction has not taken place.

What causes the reaction in chromatography?
physical change causes the reaction in chromatography!
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.
How do you change from reversed phase chromatography to normal phase chromatography?
How do you change from reversed phase chromatography to normal phase chromatography? answer:Water -------> Ethanol ---------> Acetone -----> Ethyl acetate ------>Chloroform ------->HeptaneHow to Change from normal phase to reversed phase chromatography?Heptane ------->Chloroform -------> Ethyl acetate ---->Acetone --------->ethanol -------> WaterMohammad Abdel Qader (Mousa)Lab.

How can a mixture be separated in a chemical change?
A mixture cannot be separated with chemical change because a mixture is two or more substances which will retain their physical properties when combined. Mixtures are separated by physical means like filters, sifting, chromatography, centrifuge, electrophoresis and magnetic attraction depending on what the mixture is composed of.
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
