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.

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.
What are the two types of paper chromatogaphy?
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.
Which pigment in chlorophyll moves the fastest?
Chlorophyll b typically moves faster than chlorophyll a during paper chromatography due to its higher polarity and increased ability to interact with the paper and solvent.
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 is descending paper chromatography?
ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top. similarly in descending chromatography mobile phase moving from top to bottom.
What is paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
What is ascending paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.
When using paper chromatography to separate screen methyl orange and methyl orange which one moves the furthest up the paper?
The Screened Methyl Orange moves the furthest
What leaf pigment does the yellow band on the chromatography paper represent?
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 forces cause the eluding solvent to move along the chromatography paper?
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.
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
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.
