Which one is used as stationary phase in paper chromatography?
Correct answer: D. Water absorbed on paper
- A. Alcohol
- B. Adeline
- C. Piece of paper
- D. Water absorbed on paper
Explanation
Water absorbed on paper: This option is correct. In paper chromatography, the stationary phase is usually achieved by impregnating the paper with water or a suitable aqueous solution. The water absorbed on the paper fibers acts as the stationary phase, while the mobile phase (solvent) carries the components of the sample along the paper.

About Chromatography
Chromatography separates the components of a mixture through different distributions between a stationary phase and a mobile phase. It covers paper, thin-layer and column chromatography, retention or migration behaviour, the calculation and interpretation of Rf values, and the use of colour or other detection methods to identify substances.
