Explain partition chromatography. What is partition chromatography? Describe paper chromatography.

(N/A) Partition chromatography: Partition chromatography is based on the continuous differential partitioning of components of a mixture between stationary and mobile phases. For example,paper chromatography is a type of partition chromatography.
Paper chromatography: Paper chromatography is a form of partition chromatography. $A$ special quality chromatography paper is used. In this method,a line is drawn with a pencil on the chromatography paper parallel to one edge (at a height of approximately $2 cm$ from the bottom),which is called the base line. Then,a drop of the mixture solution is applied as a small spot on this line. The spot is dried by blowing hot air over it.
After drying,the paper is placed in a closed chamber,and the edge of the filter paper is dipped into a suitable solvent (developer) for development.
Here,the solvent acts as the mobile phase and the water trapped in the cellulose fibers of the paper acts as the stationary phase. The solvent rises up the paper by capillary action and flows over the spot. The components of the mixture move upwards along with the solvent to different extents due to their different solubilities in the mobile and stationary phases,leading to their separation.
