Before you try it, think about:
What do you suspect are the components contained in the green leaves you are using?
How will the colors of the leaves behave when separated using water or isopropanol?
Feel free to write in the comments. Please observe the rules of the game.
You can also send us photos of your experiment!
Good luck!
Which piece of chalk belongs to which liquid? If you have carried out the experiment, you will surely be able to assign the pictures easily!
Have fun!
If you are unsure, compare the two before-and-after pictures using the slider on the chalk chromatography page!
Before you write a comment, take another look at the game rules.
What observations did you make during chalk chromatography?
You are welcome to write your results in the comments.
Please observe the rules of use.
Good luck!
Now you can surely answer this question:
Look at your chromatogram – into which components have the felt-tip pen colors separated?
Why does your “chromatogram” (the filter paper with the color strips) look like this, why have individual colors migrated further than others?
Have your felt-tip pen colors separated like those in our video, or did you get a different chromatogram?
