No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).
No. They need not be colored in order to be separated. If they are colored, it makes them easier to see once they are separated, but even if not colored, you can visualize the separated compounds by other means.
yes Chromatography is used to separate colours.... I had this question for homework :) i hope it helped;)
Colorless compounds can be made visible by bing allowed to react with other reagents.
Yes
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.
Chromatography comes from the Greek chrom- meaning "colored" and graph- meaning "writing" so it literally means "colored writing".
They are used in many scientific studies to identify unknown organic and inorganic compounds. They are also used in crime scene investigation, DNA and RNA sequencing, among others. Essentially, any solution can be separated through some form of chromatography.
The transition metals tend to form colored compounds.

_____ are colored chemical compounds that Osborb light
the answer is pigments
The transition metals tend to form colored compounds.
the colored compounds in them are chloroplast and chlorophyll that are colored green and absorb light for the process of photosynthesis....
compounds are responsible for the production of the colored light?
