How many pigment bands do you see in chromatography experiment?
The number of pigment bands seen in a chromatography experiment will depend on the number of different pigments present in the sample being analyzed. Each pigment will typically appear as a distinct band on the chromatogram.
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.
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
If a chromatogram is run for a longer period of timem will the Rf values increase for each pigment?
No, the Rf values will not increase for each pigment with a longer chromatography run time. The Rf value is a constant characteristic of a compound in a particular solvent system and is not affected by the duration of the chromatography run.
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.
How can you fin out if a green pigment is present in plants?
Chromatography.
Removing chlorophyll pigment from leaves might be done by?
chromatography

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 is the formula for determining the reference front of pigment?
The formula for determining the reference front of pigment in thin layer chromatography is: Reference front = distance traveled by pigment / distance traveled by solvent.

How is chromatography used to study plant pigment?
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...
What is the order of chlorophyll pigment bands from fastest to slowest?
Pigment colour Pigment Rf value orange yellow carotene 0.96 grey a breakdown product 0.70 blue green chlorophyll a 0.58 green chlorophyll b 0.48 deep yellow xanthophyll 0.44
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.
Why pigment travel shorter than other pigments in chromatography?
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.
