Question

what is the stationary phase in paper chromatography ​

Answer 1

The stationary phase in paper chromatography is the strip or piece of paper that is placed in the solvent. In thin-layer chromatography the stationary phase is the thin-layer cell. Both these kinds of chromatography use capillary action to move the solvent through the stationary phase.

Answer 2

➤ Answer :-

⟶ Stationary Phase in Paper Chromatography :-

• Chromatography is a separation process involving two phases, one stationary and the other mobile.
• Typically, the stationary phase is a porous solid (e.g., glass, silica, or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary.
• The result of paper chromatography can be explained better by the theory that indicates water as the stationary phase.
• Typically, polar molecules will have a high attraction for water and move slower than non-polar molecule, which is expected if water is the stationary phase.
