it has more affinity (attraction) to the solvent than to the paper
In a perfect vacuum, all wavelengths travel the same distance. In atmosphere, longer wavelengths (red) travel further than shorter wavelengths (blue) due to a phenomenon called Rayleigh scattering. That is why the sky is blue, and the setting sun is red. Similarly, in interstellar space (when we view light from distant stars), shorter wavelengths (blue) do not travel as far as longer wavelengths (red) due to a phenomenon called interstellar extinction. See the Related Links below for Wikipedia articles on Rayleigh scattering and interstellar extinction.
Acetone is commonly used in chromatography experiments as a solvent to dissolve the components of the sample being analyzed. It helps in the separation of different compounds present in the sample by allowing them to travel at different rates along the chromatography paper or column. Acetone also helps in achieving good resolution and sharp bands in chromatographic separations.
Left Ventricle because it has to pump the blood throughout systemic circulation.
The most common color of light produced by bioluminescent creatures is blue. This is because blue light can travel the farthest underwater, making it an effective form of communication or attracting prey in the deep sea.
A person with permission level 6 in the Defense Travel System typically has access to functions such as approving travel authorizations, processing travel claims, managing user roles and permissions, and overseeing compliance with travel policies and regulations.
Pigments travel at different rates in chromatography because of differences in their molecular size, polarity, and solubility in the solvent. Smaller, less polar pigments will travel further up the chromatography paper because they are less attracted to the stationary phase and can move more easily with the mobile phase.
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.
Pigments migrate through a process called chromatography, where they are separated based on their size and solubility in a solvent. As the solvent travels up a chromatography paper, pigments with higher solubility move faster and travel further, resulting in distinct bands of separated pigments. The migration of pigments in chromatography is based on their individual chemical properties and interactions with the solvent.
In paper chromatography for separating leaf pigments, common solvents used include a mixture of organic solvents such as ethanol, acetone, or petroleum ether, often combined with water. These solvents help dissolve the pigments, allowing them to travel at different rates along the chromatography paper based on their solubility and affinity for the paper. As the solvent moves up the paper, pigments like chlorophyll, carotenoids, and anthocyanins separate into distinct bands.
chromatography is basically a technique used for the separation of different components.... plant pigment consist of different components..... the sample is taken nd spotted over a chromatography paper..... nd den it is kept in suitable solvent to get separated...... different components travel different distance on chromatogram.... dis is how v cn use chromatography to study plant pigments...
To separate a mixture of pigments from an ink cartridge, you can use chromatography, a technique that exploits the different solubilities of the pigments. Start by dissolving the ink in a suitable solvent, then apply a small spot of the solution onto chromatography paper. When the paper is placed in a solvent (like water or alcohol), different pigments will travel at different rates, allowing them to be separated. After the solvent has moved up the paper, you can analyze the distinct spots corresponding to various pigments.
Different inks separate during chromatography because they contain different pigments with varying polarities. As the solvent moves up the paper, the pigments in the ink interact differently with the paper and solvent, causing some pigments to travel faster and further than others. This separation allows the individual pigments in the ink mixture to be identified by their distinct colors and positions on the chromatogram.

The pigment spot on chromatography paper should not be submerged in solvent because it will result in spreading and mixing of the pigments, making it difficult to distinguish them. Instead, the solvent should be allowed to slowly travel up the paper by capillary action, separating the pigments based on their solubility and mobility.
The process is called chromatography. The property is the attraction of pigments to a liquid or solution (such as water) and its ability to dissolve in the solution. In paper chromatography, a pigment that dissolves easily in water will travel farther up the paper as opposed to an oil, that does not dissolve in water.
Pigments move at different rates in chromatography because they have varying molecular weights, sizes, and polarities. Lighter, less polar pigments travel faster because they interact less with the stationary phase and are carried further by the mobile phase. Heavier, more polar pigments move more slowly as they have stronger interactions with the stationary phase.
It depend on the density of the pigments.
