The water dissolves the paper molecules.
The propelling force in paper chromatography is capillary action, where the solvent moves through the paper due to the attraction between the solvent and the paper fibers. This causes the components in the sample to separate as they are carried at different rates along the paper.
In paper chromatography n-butanol:acetic acid:water mixture in the ratio 4:1:1 is used as a solvent whereas in case of thin layer chromatography(TLC) petroleum ether and acetone in the ratio 9:1 is used as a solvent. Also, in some cases, DCM(dichloromethane is used as a solvent.
Waiting for 75 minutes in paper chromatography allows the solvent to travel up the paper, separating the different components of the mixture based on their solubility. This extended time period ensures that the components have enough time to migrate a sufficient distance for meaningful separation and analysis.
Instead of chromatography paper, you can use materials like coffee filters, filter paper, or even paper towels for paper chromatography tests. These alternative materials can absorb the solvent and help separate the components of a mixture based on their solubility and molecular properties, similar to chromatography paper.
Paper chromatography is a laboratory technique used to separate and analyze mixtures of substances. It involves applying a sample to a strip of paper, which is then placed in a solvent and allowed to separate into its individual components based on their different affinities to the paper and the solvent. The separated components can be visualized as distinct bands on the paper strip.
The two types of paper chromatography are ascending chromatography, where the solvent moves up the paper, and descending chromatography, where the solvent moves down the paper.
The component that moves the furthest in paper chromatography is the one that is most attracted to the solvent and has the least interaction with the paper. This usually means that the component is less polar than others and is better able to dissolve in and be carried by the mobile phase.

Solvent is used in paper chromatography to carry the sample mixture along the paper and separate its components based on their affinity for the solvent and the paper. As the solvent moves through the paper, it dissolves the components of the sample and allows them to separate based on their solubility and interactions with the paper.
In chromatography, pigments can be separated based on their differing affinities for the mobile and stationary phases. The different pigments will travel at different rates through the chromatography system, allowing for their separation and identification based on their unique colors and positions within the chromatogram. Pigments play a key role in chromatography as they provide a visible representation of the separation process.
The solvent moves along the chromatography paper due to capillary action, which is the result of the attractive forces between the solvent molecules and the paper. The solvent travels up the paper, carrying the components of the mixture with it as it moves through the stationary phase.

This method is called paper chromatography.
Paper chromatography is a technique used to separate and analyze different components of a mixture based on their affinity for a stationary phase (paper) and a mobile phase (solvent). The mixture is applied to a specific point on the paper and then placed in a container with a solvent that moves up the paper via capillary action, carrying the components with it. As the solvent moves, the components of the mixture are separated based on their solubility in the solvent and their interaction with the paper.

Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
