What are the relations with pigment and chromatography?
the more soluble the plant pigment is with the chromatography solvent, the farther it will travel up the chromatography paper
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...
Why do different substances travel at different speeds in a chromatography?
yes they do
Do longer or shorter restriction fragments travel farther?
shorter
If the Rf factor of a pigment is .8400 and the distance that the solvent traveled is 12 cm how far did the pigment travel?
10.08

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.
Why does carotene travel farthest in chromatography of leaf pigments?
it has more affinity (attraction) to the solvent than to the paper
What two factors determine the rate at which the pigments travel up the chromatography paper?
Rf value. polarity of solvent
Why do some pigments move farther up the chromatography strip than others?
Different pigments are not equally soluble in the solvent. Also because they are attached to the fibers of the paper differently (hydrogen bonds, etc). Therefore, the pigments move at different rates. The more soluble the pigment, the farther up the pigment will move.
What do the Rf values indicate about the relative solubility of the pigment in the the solvent?
The Rf values do not indicate the solubility of a substance. The Rf value or retardation factor is the ratio of the distance traveled by the center of a pot to the distance traveled by the solvent front in chromatography.
Why do pigments travel different distances up filter paper?
It depend on the density of the pigments.
Why do different substances travel at different speeds in a chromatography?
yes they do
Do longer or shorter restriction fragments travel farther?
shorter
If the Rf factor of a pigment is .8400 and the distance that the solvent traveled is 12 cm how far did the pigment travel?
10.08
Why do different colors travel at different speeds?
The paper is made of cellulose, a polar substance, and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far. found on <http://en.wikipedia.org/wiki/Chromatography>
