steps to do a chromagraphy ink separation
Solution
Sure, here are the steps to perform a chromatography ink separation:
-
Gather your materials: You will need a strip of filter paper, a black (or any color) water-soluble marker, a pencil, a tall glass, table salt, water, and a measuring spoon.
-
Prepare your solution: Dissolve about 1/8 teaspoon of table salt in 3 cups of water. This will be your chromatography solution.
-
Prepare your filter paper: Draw a line with your pencil about 1 inch from the bottom of the filter paper. Then, make a dot with your marker on the center of the line.
-
Immerse the paper: Place the filter paper in the glass with the pencil line at the top and the marker dot at the bottom. Make sure the marker dot is above the surface of the chromatography solution.
-
Wait for the separation: The solution will start to travel up the paper, bringing the ink with it. As the ink's components have different properties, they will travel at different speeds, causing them to separate.
-
Analyze the results: Once the solution has almost reached the top of the paper, remove it from the glass and let it dry. You will see different colors on the paper, which are the different components of the ink.
Remember to always handle the materials with care and clean up your workspace when you're done.
