Paper chromatography is a technique used to separate and analyze mixtures of substances based on their different solubilities and interactions with a stationary phase. In this case, paper chromatography can be used to separate insoluble solid chalk from a liquid solution of chalk by using filter paper as the stationary phase.
To perform paper chromatography to separate chalk from a liquid solution of chalk, the following steps can be followed:
1. Prepare a filter paper strip by cutting a piece of filter paper into a rectangular shape and drawing a horizontal line near the bottom of the paper using a pencil.
2. Prepare the liquid solution of chalk by dissolving chalk in a solvent such as water or ethanol. The chalk should be completely dissolved in the solvent to form a homogeneous solution.
3. Place a small spot of the liquid solution of chalk on the horizontal line drawn on the filter paper using a capillary tube or a dropper. Allow the spot to dry completely.
4. Prepare a developing chamber by placing a small amount of solvent in a container with a lid. The solvent should be chosen based on its ability to separate the components of the mixture effectively.
5. Place the filter paper strip with the spot of the liquid solution of chalk facing downwards into the developing chamber. Ensure that the spot does not come into contact with the solvent.
6. Close the lid of the developing chamber and allow the solvent to move up the filter paper strip through capillary action. The solvent will carry the components of the mixture along with it, separating them based on their solubilities and interactions with the filter paper.
7. Once the solvent has reached the top of the filter paper strip, remove the strip from the developing chamber and allow it to dry completely.
8. The separated components of the mixture will appear as distinct spots or bands on the filter paper strip. The insoluble solid chalk will be separated from the liquid solution of chalk based on its interactions with the filter paper and the solvent.
By analyzing the position and characteristics of the spots or bands on the filter paper strip, the insoluble solid chalk can be identified and separated from the liquid solution of chalk using paper chromatography.
