The yellow band on chromatography paper typically represents the pigment xanthophyll, which is a type of carotenoid. Xanthophylls are responsible for the yellow coloration in many plants and play a role in photosynthesis by helping to protect the chlorophyll from excessive light. This pigment is often found in various green plants, contributing to the overall coloration of leaves.

What are the relations with pigment and chromatography?
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.
What pigment is most soluble?
assuming you used an ether based chromatography solution it will be the pigment that is at the top of the chromatography paper
Will water extract pigment in a chromatography?
Yes, water can extract pigment during chromatography. This technique uses a solvent to separate and analyze mixtures, and water is often used as the solvent for certain types of pigments. Water's polarity can help separate different pigments based on their solubility and interactions with the paper or gel used in chromatography.
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.
What can you use instead of chromatography paper in a paper chromatography test?
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.
How to make yellow paper?
Yellow paper is typically made by adding a yellow dye or pigment to the paper pulp during the papermaking process. The dye or pigment is mixed in with the pulp before it is pressed and dried, resulting in yellow-colored paper.
What will be the color of a sheet of paper containing red pigment when yellow light shines on it?
The red pigment in the paper will absorb all colors except red, which will be reflected. When yellow light shines on the paper, which contains red pigment, the red pigment will absorb the other colors in the yellow light spectrum but reflect the red light. So, the paper will appear red under yellow light.
What determines the distance a pigment moves up the paper?
The distance a pigment travels up the paper in paper chromatography is determined by its solubility in the solvent being used, its molecular size, and its attraction to the paper. Pigments that are more soluble and smaller in size tend to move further up the paper, while those with stronger interactions with the paper tend to stay closer to the origin.
Which determines the speed with which a pigment moves up the chromatography paper?
Chromatography is a technique that separates molecules from each other on the basis of their solubility in particular solvents. As a nonpolar solvent moves up the chromatography paper, the pigment moves along iwth it. The more non-polar a pigment, the more soluble it is in a nonpolar solvent, and the faster and father it proceeds up the chromatography. Pg 94, laboratory 8.1, Inquiry into Life, Sylvia S. Mader, laboratory manual, 12th edition
What will be the color of a paper containing red pigment when yellow light shine on it?
The paper containing red pigment will appear red when yellow light shines on it. This is because red pigment absorbs most colors of light except red, which it reflects. So, the red pigment on the paper will reflect red light and appear red when illuminated by yellow light.
How can I make paper yellow?
You can make paper yellow by using yellow dye or pigment during the paper-making process. Alternatively, you can also soak the paper in a yellow dye solution after it has been made.

Water's polarity can help separate different pigments based on their solubility and interactions with the paper or gel used in chromatography.
Why one pigment moves faster than the other in paper chromatpgraphy?
The speed at which pigment molecules move during paper chromatography is determined by their size, shape, and polarity. Smaller, less polar molecules will typically move faster than larger, more polar molecules because they can more easily pass through the pores of the paper. Additionally, the interactions between the pigment molecules and the solvent used in the chromatography process will also affect their speed of movement.
What property of the ink was used to separate the colours?
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.
What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.
