What happens when paper chromatography is left in the solution?
If paper chromatography is left in the solution, the solvent will continue to move up the paper by capillary action. This can lead to the separation of the components in the mixture to a greater extent. Additionally, the colors may spread out and further separate along the paper.
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.
What pigment is most soluble?
assuming you used an ether based chromatography solution it will be the pigment that is at the top of the chromatography paper
How do you use chromatography to show how many colors were in the solution?
It depends what sort of solution and what sort of chromatography. Assuming it's something simple like ink you'd usually use a piece of paper or filter paper. You'd apply a spot of your analyte (the solution being analysed) at a short distance from the bottom of the paper, then put the paper in a beaker or similar container with a small amount of ethanol, water or another solvent in the bottom. Ensure that the solvent does not go above the level of the spot of analyte. The solvent will be drawn up through the paper by capillary action, and will draw the different parts of the analyte with it and deposit them at different distances from the initial spot. Stop the experiment by removing the paper from the beaker once the solvent front (the horizontal line where the highest wet part of the paper is) reaches the top of the paper.
Why wait for the solvent to move almost to the top of the paper before removing it from the chamber in chromatography?
Waiting for the solvent to move almost to the top of the paper in chromatography ensures optimal separation of the components in the mixture. This allows sufficient time for the different substances to travel varying distances based on their affinities for the stationary phase and the solvent. Removing the paper too early may result in incomplete separation, making it difficult to distinguish between the components. Additionally, achieving a clear separation helps in accurately measuring the retention factor (Rf) values for analysis.
What is descending paper chromatography?
ascending chromatography is a type of chromatography in which chromatic substance is in mobile phase and moving from bottom to top. similarly in descending chromatography mobile phase moving from top to bottom.

How do you stop your meringue sticking to the paper?
Put a sheet of wax paper on top of each layer (if you're stacking it).

What determines how far a substance moves on a chromatogram gram?
The substance moves according to the solubility of the substance. For example, dye a's solubility is water is high, it will reach the top of the chromatogram. If the dye is not soluble in water or low solubility in water, it will stop half way on the chromatography paper and/or will separate from the other dyes.
What is the Latin word for reaching the top?
Indipiscor apex, roughly 'reaching (the) top'.
What does clay after reaching the top of the slide?
After reaching the top of the slide he found a Pine tree
What does Clay find after reaching the top of the slide?
After reaching the top of the slide he found a Pine tree

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.
