Show Hint
Paper Chromatography is a type of partition chromatography. Chromatography paper contains water trapped in it, which acts as the stationary phase. The paper selectively retains different components according to their differing partition in two phases.
- Adsorption chromatography
- Partition chromatography
- Thin layer chromatography
- Column chromatography
The Correct Option is B
Solution and Explanation
Paper chromatography is an example of Partition chromatography.
The principle of paper chromatography involved is partition chromatography, in which the substances are distributed or partitioned between the liquid phase and the stationary phase. Water is one of the phases, which is held in the pores of the filter paper used, while the other is the mobile phase which moves over the paper.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Concepts Used:
Purification of Organic Compounds
We commonly use these methods for the purification of substances:
- Simple crystallization - The most common method that we use to purify organic solids.
- Fractional crystallization - It is the process of separation of different components of a mixture by repeated crystallisations.
- Sublimation - Certain organic solids on heating directly change from solid to vapor state without passing through a liquid state. These substances are sublimable. This process is sublimation.
- Simple distillation - It is the joint process of vaporization and condensation.
- Fractional distillation - It is the process to separate a mixture of two or more miscible liquids which have boiling points close to each other
- Distillation under reduced pressure
- Steam distillation
- Azeotropic distillation
- Chromatography
