Question
Identify the technique of separation, which is shown in the below picture.
- Separation by using solvent
- Evaporation
- Chromatography
- Sedimentation
Hint:
In the given picture we can see different colors on a sheet of paper, separating out.
The correct answer is: Chromatography
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 the given picture we can see different colors on a sheet of paper, separating out. This is the chromatography technique.
