Chromatography in which stationary phase is solid is called:
A.Partition chromatography
B.Paper chromatography
C.High pressure
D.Adsorption chromatography

Hint: Chromatography is a technique used to separate a mixture of compounds. The mixture of the compounds is dissolved in a solvent called as mobile phase, which transports it through another stationary material called as stationary phase.

Complete answer:
-In chromatography the principle involved is partition chromatography or adsorption chromatography.
-In partition chromatography the mixture of substances are partitioned or distributed between two different solvents of different polarity.
-In Partition chromatography two different phases are going to involve.
-The two different phases are mobile phase and stationary phase.
-Generally solid stationary phase is used in paper chromatography.

So, the correct option is B.

Additional information:
-Applications of paper chromatography are
-Paper chromatography is used to study the process of fermentation and ripening.
-It is used to check the purity of medicines in pharmaceutical industries.
-To inspect the quality of cosmetics.
-To detect the contaminants present in drinks and foods.
-To examine the status of the reaction mixtures in biochemical laboratories.
-To determine the drug content in human and animal blood.

Note:
The paper used in paper chromatography is Watt Mann number 1 filter paper.
By using paper chromatography we can separate a mixture of compounds into individual based on the retardation factor (\[{{R}_{f}}\]). The \[{{R}_{f}}\]value is going to depend on the polarity of the compounds present in the mixture.
