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.
Why was the blue dye more soluble than the yellow dye in the screened methyl orange by paper chromatography?
The solubility of dyes in paper chromatography depends on their chemical structure and polarity. The blue dye likely has a higher affinity for the solvent used in the chromatography process, making it more soluble than the yellow dye. Additionally, the molecular interactions between the blue dye and the solvent could be stronger, allowing it to travel further up the paper. In contrast, the yellow dye may have stronger interactions with the stationary phase, leading to lower solubility and reduced mobility.
Why does red ink travel further than yellow ink in chromatography?
Red ink travels further than yellow ink in chromatography because red ink has a lower affinity for the stationary phase (paper) and a higher affinity for the mobile phase (solvent). This causes the red ink molecules to move more easily and quickly through the paper. Yellow ink, on the other hand, has a stronger attraction to the stationary phase, resulting in slower movement and shorter distance traveled.
Why the descending method of chromatography is faster than the other method?
Descending chromatography is faster because gravity aids in pulling the solvent down through the stationary phase, allowing for quicker elution of compounds. In this method, the analytes travel with the solvent flow, resulting in faster separation compared to ascending chromatography where the solvent has to move against gravity.
In chromatography how are the sunstances carried up the paper?
The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others.
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.
Why does carotene travel farthest in chromatography of leaf pigments?
Carotene travels the farthest in chromatography of leaf pigments because it is the least soluble in the chromatography solvent. This means it interacts less with the solvent and more with the chromatography paper, allowing it to move further up the paper before the solvent front stops it.
Can a helicopter travel farther than airplane?
Most airplanes can travel further than helicopters.
Why does the color blue travel faster in carnations than other colors?
how fast does the colour blue travel
Does the space shuttle travel further than the moon?
No
Why is the orbit of Saturn longer than that of Jupiter?
Because it is further from the Sun than Jupiter and thus has further to travel.
Why does red ink travel further than yellow ink in chromatography?
Red ink travels further than yellow ink in chromatography because red ink has a lower affinity for the stationary phase (paper) and a higher affinity for the mobile phase (solvent). This causes the red ink molecules to move more easily and quickly through the paper. Yellow ink, on the other hand, has a stronger attraction to the stationary phase, resulting in slower movement and shorter distance traveled.
Which color pigment will travel the farthest?
In a perfect vacuum, all wavelengths travel the same distance. In atmosphere, longer wavelengths (red) travel further than shorter wavelengths (blue) due to a phenomenon called Rayleigh scattering. That is why the sky is blue, and the setting sun is red. Similarly, in interstellar space (when we view light from distant stars), shorter wavelengths (blue) do not travel as far as longer wavelengths (red) due to a phenomenon called interstellar extinction. See the Related Links below for Wikipedia articles on Rayleigh scattering and interstellar extinction.
What are the benefits of a steam train?
You can travel faster than a horse or a carriage and you can travel further wasting small energy.
Why can't an RF value of more than 1 be calculated?
An RF (retention factor) value greater than 1 cannot be calculated because it represents the ratio of the distance traveled by a compound to the distance traveled by the solvent front on a chromatography plate. If a compound travels further than the solvent front, it suggests that the compound has not interacted properly with the stationary phase, which is not a valid scenario in chromatography. Therefore, RF values are always between 0 and 1, indicating that the compound can only travel a distance equal to or less than the solvent front.
Why the descending method of chromatography is faster than the other method?
Descending chromatography is faster because gravity aids in pulling the solvent down through the stationary phase, allowing for quicker elution of compounds. In this method, the analytes travel with the solvent flow, resulting in faster separation compared to ascending chromatography where the solvent has to move against gravity.
