Question 69

Given below are two statements : Statement (I): In partition chromatography, stationary phase is thin film of liquid present in the inert support. Statement (II) : In paper chromatography, the material of paper acts as a stationary phase. In the light of the above statements, choose the correct answer from the options given below :

Statement I: In partition chromatography, the stationary phase is a thin film of liquid present on an inert support. This is correct - partition chromatography is based on the partitioning of components between a liquid stationary phase held on a solid support and a mobile phase.

Statement II: In paper chromatography, the material of paper acts as the stationary phase. This is incorrect. In paper chromatography, the water trapped in the cellulose fibers of the paper acts as the stationary phase (liquid), not the paper material itself. Paper chromatography is actually a type of partition chromatography.

The correct answer is Option 1: Statement I is true but Statement II is false.
