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?

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.
How do you obtain a concentrated sample of the ink to run a chromatogram?

What would happen if the beaker is left uncovered during the development of the chromatogram?
Bad things happen. The mobile phase evaporates and thus it's composition changes. The vapor phase above the chromatogram is not saturated or at equilibrium, and this affects the movement of the sample on the solid phase.
