MCQ on Paper Chromatography

MCQ on Paper Chromatography: Paper chromatography is a separation technique that separates the molecules based on solubility in the stationary phase and mobile phase.

The stationary phase coats the paper fibers with a thin layer, and the movement of the liquid mobile phase occurs along the paper layer under the action of capillary forces. Organic solvents, miscible or immiscible with water, water, or electrolyte solutions are used as the mobile phase.

In the stationary phase, a substance can be retained both due to dissolution in water contained in the paper, and due to adsorption by the paper.

If the distribution of the components of the analyzed mixture between the two phases is different, then the movement of the zones of these components along the paper occurs at different speeds, which leads to separation.

The position of individual zones (spots) on the chromatogram is characterized by the value of Rf (Retention Factor). Below we are provided MCQ on Paper Chromatography.
