❶None of the components travels as fast as the water itself - you can see that the paper is damp much further than any part of the ink has reached. So the fibres exert a different drag on the different components of the ink.

For example this experiment used water soluble and lipid soluble solvents. This means that when one of these solvents are present in the trial, only that type of pigment will travel with the movement of the solvent lipid soluble solvent with lipid soluble pigment and water soluble solvent with water soluble pigment.

The beat leaf contained more pigments in the leaf compared to the spinach leaf. This could be because the beat has a root where it stores starch. This would require it to undergo photosynthesis more times in order for its to create more glucose to store. The increased number of accessory pigments allows for a wider range of light to be taken in and converted into energy excitation of electrons on the chlorophyll for the photosynthetic process.

Chlorophyll A and B. In all chromatographic separations, there is an important relationship between the solvent, the chromatography paper, and the mixture. For a particular mixture, the solvent and the paper must be chosen so the solubility is reversible and be selective for the components of the mixture.

The main requirement, though, of the solvent is to dissolve the mixture needing to be separated. For the separation of a mixture, the substances making up the mixture must be evenly dispersed in a solution, a vapor, or a gas.

Once all of the above criteria have been met, chromatography can be a simple tool for separating and comparing chemical mixtures. Materials The materials used for this lab are paper, pencil, eraser, filter paper, test tube, rubber stopper, paper clip, metric ruler, black felt-tip pen, and a computer.

Methods The first step of the method is to bend a paper clip so that it is straight with a hook at one end. Push the straight end of the paper clip into the bottom of the rubber stopper. Next, you hang a thin strip of filter paper on the hooked end of the paper clip.

Insert the paper strip into the test tube. The paper should not touch the sides of the test tube and should almost touch the bottom of the test tube.

Now you will remove the paper strip from the test tube. Draw a solid 5-mm-wide band about 25 mm from the bottom of the paper, using the black felt-tip pen. Use a pencil to draw a line across the paper strip 10 cm above the black band. Pour about 2 mL of water into the test tube. The water will act as a solvent. Put the filter paper back into the test tube with the bottom of the paper in the water and the black band above the water.

Observe what happens as the liquid travels up the paper. Record the changes you see. When the solvent has reached the pencil line, remove the paper from the test tube. Measure how far the solvent traveled before the strip dries.

Paper Chromatography Introduction The purpose of this experiment is to observe how chromatography can be used to separate mixtures of chemical substances. Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause .
