What is paper chromatograph?
Ascending paper chromatography is where a chromatogram rises, or ascends. The paper moves up because the solvent moves it in an upward direction.

Where on the filter paper do you expect the larger molecules to be located in the final chromatogram?
Towards the centre of the chromatogram. The smaller molecules are more mobile and appear towards the outside of the chromatogram.
What are two ways of identifying amino acids on a chromatogram?
Two ways of identifying amino acids on a chromatogram are paper and gas.
3 Why do the pigments become separated during the development of the chromatogram?
The chromatogram, or chromatography paper has solvent on it. Each pigment will separate itself from the others due to the relative solubility of that particular pigment.
Why must the chromatogram be removed before the solvent travels the entire length of the paper?
So that you can measure how far it traveled.
Why should you not touch chromatogram paper with your hands?
it is because sweat and other substances especially colored ones may be present there. so it is best not to touch chromatogram papers to aviod contaminating it and getting erroneous results..:) chem.student..:)
What is The appearance of chromatograms in paper chromatography?
The chromatogram in paper chromatography is just the paper itself. You can look at the paper and see the dots that have risen due to the solvent. The appearance is just simply a piece of paper with dots that have risen from the baseline to a certain spot on the paper. see related link below for more info
Why the beaker covered during the development of chromatogram?
During the development of a chromatogram, it is better to cover it with a beaker to prevent evaporation, which will affect the movement of the solute and solvent system. This will ensure that the chromatogram will develop properly.
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 purpose of spraying the chromatogram with a 0.2 percent ninhydrin solution?
Ninhydrin solution is used and sprayed on the filter paper or any paper used to make the position of the amino acids clearly visible. This is followed by measuring the distance of migration.
What do you call the horizontal layout of the paper in page set up?
landscape view
