Could the presence of different pigments be detected before separation by chromatography?
Yes, the presence of different pigments can be detected before separation by chromatography through techniques such as UV-Vis spectroscopy or fluorescence spectroscopy. These techniques can provide information about the absorption or emission properties of the pigments present in a sample.

How many different pigments might be identified through the separation process?
Hundreds of different pigments can be identified through the separation process using techniques like chromatography or spectrophotometry. Pigments such as chlorophyll a, chlorophyll b, carotenoids, and anthocyanins are commonly detected in plants.
What will chromatography do to the pigments in the plant extract?
Chromatography will separate the pigments in the plant extract based on their different affinities for the stationary and mobile phases. This separation will allow for the identification and quantification of individual pigments within the extract.
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.
Why do you crush leaves in paper chromatography?
Crushing leaves in paper chromatography helps to release pigments from the cells, making them available for separation on the chromatography paper. This allows for a more accurate analysis of the different pigments present in the leaves.
What is the uncontrolled variable in paper chromatography of pigments?
The temperature of the room could be an uncontrolled variable in paper chromatography of pigments, as it can affect the rate at which the solvents evaporate and the separation of the pigments on the paper. Temperature fluctuations could lead to inconsistent results in the chromatography process.

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...
How can you explain the presence of the colors on the chromatogram that are absent in the original leaf?
The presence of colors on the chromatogram that are absent in the original leaf can be attributed to the separation of various pigments during the chromatography process. When the leaf extract is applied to the chromatography medium, different pigments travel at different rates based on their solubility and affinity for the stationary phase. This separation reveals pigments that may not be visually dominant in the leaf sample but are still present in smaller quantities. Additionally, some pigments may be masked by others in the original leaf, becoming visible only after separation.
Do different flowers have different pigments by paper chromatography?
Yes, different flowers have different pigments, such as chlorophyll, carotenoids, and anthocyanins, which can be separated and identified through paper chromatography. Paper chromatography is a common technique used to separate and analyze pigments based on their solubility and interaction with the paper and solvent system.
Why did the separation of pigments in the spinach extract occur as it did?
The separation of pigments in the spinach extract occurred due to differences in their solubility and affinity for the chromatography medium. Each pigment, such as chlorophyll a, chlorophyll b, and carotenoids, interacts uniquely with the solvent and the stationary phase, causing them to travel at different rates. As the solvent moves up the chromatography paper, the pigments are carried along but separate based on these varying interactions, resulting in distinct bands of color.
What charge is carried by the pigments in the separation(biology)?
In the separation of pigments, such as during chromatography, the pigments often carry a negative charge. This is due to the presence of functional groups in the pigments that can ionize in solution, allowing them to interact differently with the stationary and mobile phases based on their charge and polarity. The varying charges and polarities of the pigments contribute to their differential movement through the medium, leading to their separation.
Why do different inks separate while using chromatography?
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.
What chemicals are used for separation of leaf pigments in paper chromatography?
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.
