How are pigments carried up filter paper?

Why do pigments travel different distances up filter paper?
It depend on the density of the pigments.
How do they make colored paper?
Colored paper is made by adding pigments or dyes to the paper pulp during the papermaking process. The pigments or dyes are mixed in with the pulp before it is processed and dried, resulting in the paper having a colored appearance. Different colors can be achieved by using different pigments or dyes in the papermaking process.
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 :)
How could you determine if the inks contain the same mixture of pigments?
You could try experimenting with chromatography.Cut strips of filter paper or paper napkinPut a dot of each ink a small ways in from the end of a stripPut that end (but not the dot of ink) into a liquid that may dilute at least some of the liquid in the ink: Suggestions : do different strips with water, alcohol, other solventsCompare the results after some time,The liquid solvent will carry different pigments different distances along the paper substrate and will most probably show differences for different inks.
Why does markers change the color of the paper when dipped in water?
Because the pigments found in the marker are sperated by capillary action. So basically all the different pigments found in that one maker are spread on the paper. :)
The laboratory technique is used to separate the different pigments in a green leaf?
Chromatography is the laboratory technique used to separate the different pigments in a green leaf. The leaf pigments are separated based on their solubility in the solvent used. By analyzing the bands of separated pigments, researchers can identify and quantify the different pigments present in a leaf.
Why did different dyes travel up the filter paper at different rates in paper chromatography?
different dyes travel with different speed/rates on filter paper in paper chromatography as they have nothing to do with the filter paper as it is the stationary medium while the rates depends upon the interaction between the solute i.e., dyes and the mobile phase i.e., the solvent.
Can sand go through filter paper?
Oil can pass through filter paper. Also bear in mind that there are different grades of filter paper. I personally have filtered oil very successfully, using an ordinary paper towel as my filter paper.
How do they do paper?
they dye the paper using inks and pigments
How is paper made into different colours?
Paper can be made into different colors by adding pigments or dyes to the pulp during the papermaking process. These additives color the fibers, resulting in paper of different hues. Alternatively, paper can be dyed or painted after it has been formed and dried.
Where available filter paper for test petrol quality?
This filter paper is not so important, you can use different types. An example is Whatman grade 2 filter paper; see the link below.
