    1. Solubility: Substances in the mixture have different solubilities in the solvent (mobile phase). More soluble substances travel further up the paper because they dissolve more easily in the solvent.

    2. Affinity for the Stationary Phase: The paper acts as the stationary phase, and different substances in the mixture have varying degrees of interaction with the paper. Some substances have a stronger attraction (affinity) to the paper, causing them to move more slowly, while others move faster because they have weaker interactions with the stationary phase.

    Thus, the combination of solubility in the solvent and affinity for the stationary phase leads to the separation of substances as they move at different rates during the chromatography process.

  • Solubility

  • The paper (stationary phase) has a certain level of attraction for different substances. Substances that are more attracted to the paper will move more slowly, while those less attracted will travel faster.

  • This suggest that the marker is soluble in water
