The problem that will be created if you mark the origin line with a washable felt-tip marker until after you discover that the solvent front has reached the top of the paper is that the marker ink may dissolve and spread along with the solvent, leading to inaccurate and unreliable results in your experiment.

When conducting chromatography, the origin line is marked on the paper to indicate where the samples are applied. The purpose of marking the origin line is to ensure consistency and accuracy in analyzing the results. However, using a washable felt-tip marker means that the ink is not intended to be permanent.

If the solvent front reaches the top of the paper before marking the origin line, the ink from the marker may dissolve and spread with the solvent. This can cause unwanted interference and smudging in the chromatogram, making it challenging to identify and interpret the separated components accurately.

To avoid this problem, it is crucial to mark the origin line with a permanent marker or any other reliable method before starting the chromatography process. This way, the markings will remain intact even with the movement of the solvent front, ensuring clear and precise results in your experiment.
