Question
In chromatography, the filter paper which is used acts as
- A mobile phase
- A solid phase
- A liquid phase
- A stationary phase
Hint:
Mobile phase runs through the filter paper.
The correct answer is: A stationary phase
Chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.
In chromatography, the filter paper which is used acts as a stationary phase.
