Question
11.If a substance does not move from the start line, what does this tell you about the substance in the solvent?
Solution
If a substance does not move from the start line in a chromatography process, it suggests that the substance is not soluble in the solvent being used, or has no affinity for the solvent. This means the substance and the solvent do not interact, hence the substance remains at its initial spot.
