Question
What method would you use to separate a mixture of inks?
Solution
The method used to separate a mixture of inks is called chromatography. Here are the steps:
-
Cut a strip of filter paper or chromatography paper.
-
Draw a line near the bottom of the paper using the ink that needs to be separated.
-
Pour a small amount of solvent (like water or alcohol) into a glass or beaker. The level of the solvent should be lower than the line of ink.
-
Place the strip of paper into the glass or beaker with the ink line at the top. The solvent will start to travel up the paper.
-
As the solvent rises, it will carry the ink with it. Different components of the ink will move at different rates, thus separating the ink into its individual components.
-
Once the solvent has almost reached the top of the paper, remove the paper from the solvent and allow it to dry.
-
The different colors seen on the paper represent the different components of the ink. This process is called paper chromatography.
