AIIMS 2019 Chemistry Paper Chromatography MCQ Question

In paper chromatography, the stationary phase refers to the solid medium (the paper) that does not move, while the mobile phase consists of the solvent that travels through the stationary phase, carrying the analytes with it. The statement that it is a stationary phase is incorrect because it implies that the stationary phase is dynamic, which contradicts the fundamental principle of chromatography where the stationary phase remains fixed. Since all options are marked as N/A, they do not provide any alternative explanations or correct statements, reinforcing that the focus should be on understanding the roles of stationary and mobile phases in the chromatography process.
