How can you tell from a chromatogram how many coloured substance there are in a drink?
gfrg s
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.
Would a pure substance show more than one color or spot in a chromatogram. explain?
yes.
What is locating agent used for?
Locating agent is a substance/liquid that help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
Why it is necessary to spray a chromatogram with a locating agent?
It help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
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.
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 are two ways of identifying amino acids on a chromatogram?
Two ways of identifying amino acids on a chromatogram are paper and gas.
What can go wronge in chromatogram?
you spelling wrong wrong
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 is process of chromatography benefit to humans?
It can help in the purification of substance that are soluble in any solvent and also this helps because every substance has a different retention factor so they will all appear on different levels in the chromatogram this is used in the field of medicine to obtain extremely pure chemicals for the production of drugs.

What is used to identify the purity of a substance?
The purity of any substance can be checked through Melting Point,Boiling Point or Chromatography. As A pure substance has a set and exact melting point and boiling point and a pure substance shows only one spot on the chromatogram.
