Question

An analytical method, which is used to separate colored chemicals or substances is known as-?

• A. Column chromatography
• B. Thin layer chromatography
• C. Paper chromatography
• D. Gas chromatography

Answer 1

The correct option is C Paper chromatography

Paper chromatography is an analytical method which is used to separate colored chemicals or substances. In this type of chromatography, a high quality filter paper is used as a stationery phase.

When a colored chemical sample is placed on the filter paper and it is then dipped into a solvent. The solvent will then diffuse up the filter paper, dissolving the various types of molecules present in the sample, based on the polarity of the molecule and the solvent.

And thus, the colored chemicals will be separated.
