AP Chemistry 3.9 A Explain the Results of a Separation Experiment Based on Intermolecular Interactions Questions question 1

[Maximum number: 1]

A student conducts a chromatography experiment and needs to prepare 100.0 mL of 0.340 M NaCl(a q) to use as the solvent.

A second student conducts the same chromatography experiment but removes the chromatography paper from the chamber after 15 minutes instead of 30 minutes. Predict the effect, if any, this would have on the separation distance between compounds X and Y in the new experiment. Explain your reasoning.
