A porous solid used in chromatography is typically a stationary phase, such as silica gel or alumina. These materials have a high surface area and microscopic pores that allow for the separation of different compounds based on their size, polarity, or other chemical properties. In techniques like column chromatography or thin-layer chromatography, the porous solid facilitates the movement and interaction of the analytes with the mobile phase, leading to effective separation.

What is a zeolite?
A zeolite is any of several minerals which have a porous structure, such as aluminosilicates of sodium, potassium, calcium or magnesium, which are used in water softeners and ion exchange chromatography.
What is the difference between partition chromatography and adsorption chromatography?
The partition chromatography involves separation between liquids while adsoption chromatography involves solid and liquid separations. Answer: Partition Chromatography is a liquid liquid extraction which involves two solvents while adsorption chromatography is a liquid solid extraction which involves a solid stationary phase & a liquid mobile phase.
What the different from Porous Alumimium to aluminum?
Porous aluminum has a sponge-like structure with small interconnected pores, while solid aluminum is a dense, homogeneous material without pores. Porous aluminum has a higher surface area and can be used for applications such as filtration, catalysis, and energy storage, while solid aluminum is commonly used in structural applications due to its strength and durability.
What is the method to separates the mixture?
One common method to separate a mixture is through filtration, where a porous barrier is used to separate solid particles from a liquid. Another method is distillation, which involves heating the mixture to separate components based on their boiling points. Additionally, chromatography can be used to separate components based on their different affinities for a stationary phase.

The process of using porous paper to separate molecules based on their size and ability to dissolve in a solvent is called?
The process is called chromatography. It is a technique used to separate and analyze mixtures based on their differential affinities for a stationary phase (the porous paper) and a mobile phase (the solvent).
How is paper chromatography used in everyday life?
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
Why are silica gels used in chromatography?
Silica gels are used in chromatography because of their high surface area and porous structure, which allows for good separation of different compounds based on their interactions with the silica surface. The silica gel can be modified to have different polarities, making it suitable for a wide range of chromatographic separations. Additionally, silica is chemically inert and stable, making it a reliable stationary phase for chromatography.
What is the column material in gel filtration chromatography?
The column material in gel filtration chromatography is typically composed of porous beads made from materials like agarose or dextran. These beads vary in size and create a porous network that separates molecules based on their size as they pass through the column.
What is the stationary phase in gel electrophoresis?
Stationary Phase is a layer or coating on the supporting medium that interacts with the analytes and is fixed in a place either in column or a planar surface. It can be solid, liquid, gel or solid-liquid mixture.
What paper chromatography employs the attraction of the surface of a liquid to the surface of a solid?
Chromatography - The separation of components of a mixture based on how quickly different molecules dissolved in a mobile phase(liquid surface) solvent move along a solid phase(solid surface).
What is porous solids?
porous is actually adjective which means having pores.porous solids are those solids which has porous nature.for instance alight soft foam.another characteristic of porous solids is that they absorb water like cotton so it is also a porous solid............
