Pigments are carried up the filter paper during chromatography due to a combination of their solubility in the solvent and their interaction with the paper. As the solvent moves up the paper by capillary action, it dissolves the pigments and transports them along with it. Different pigments have varying affinities for the paper and the solvent, causing them to travel different distances, which allows for their separation and identification. This process relies on the principles of differential migration based on polarity and solubility.

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.
How do you separate a mixture of pigments from an ink cartage?
To separate a mixture of pigments from an ink cartridge, you can use chromatography, a technique that exploits the different solubilities of the pigments. Start by dissolving the ink in a suitable solvent, then apply a small spot of the solution onto chromatography paper. When the paper is placed in a solvent (like water or alcohol), different pigments will travel at different rates, allowing them to be separated. After the solvent has moved up the paper, you can analyze the distinct spots corresponding to various pigments.
What pieces of lab equipment are used to set up a filtration apparatus?
Büchner funnel, filter paper, flask or beaker.
How do pigments migrate?
Pigments migrate through a process called chromatography, where they are separated based on their size and solubility in a solvent. As the solvent travels up a chromatography paper, pigments with higher solubility move faster and travel further, resulting in distinct bands of separated pigments. The migration of pigments in chromatography is based on their individual chemical properties and interactions with the solvent.
Some components of ink are minimally attracted to the stationary phase and very soluble in the solvent Where are these components located on the filter paper during chromatography?
These components would travel the farthest up the filter paper in chromatography because they are less attracted to the paper and more attracted to the solvent. They are likely to be found closer to the top of the paper where the solvent front has reached.
How are different pigments carried up filter paper?
Pigments are not carried up filter paper, dyes are. But they are carried up in solvents.
How are pigments carried up filter paper?
tatii
Why do pigments travel different distances up filter paper?
It depend on the density of the pigments.
Why are pigments carried different distances?
Because its not all the same colour so it travels up the paper and then you can see what the answer it :) I'm a high level student in science and ca answer and questions you ask me :)
Why must the solvent front be near the top of the filter paper?
Having the solvent front near the top of the filter paper ensures that the separation process is efficient by allowing the components to be carried up the paper evenly. This helps prevent overlap of the separated components and ensures a clear resolution of the different compounds in the mixture.

Filter paper? Look it up on google.

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.
Why can the pigment spot on chromatography paper not be submerged in solvent?
The pigment spot on chromatography paper should not be submerged in solvent because it will result in spreading and mixing of the pigments, making it difficult to distinguish them. Instead, the solvent should be allowed to slowly travel up the paper by capillary action, separating the pigments based on their solubility and mobility.

Büchner funnel, filter paper, flask or beaker.
How do you separate ink in colour?
you put ink on the bottom of the chromatography paper and dip one end of of it into water and leave it to stoke up the paper, separating the ink pigments
