THE CHROMATOGRAPHY SEPARATION OF INK IS BASED ON THE ABILITY OF THE COMPONENTS TO

  • A. React with solvent
  • B. React with each other
  • C. Dissolve in each other in the column
  • D. Move at different speeds in the column ✓

 

The answer to the question is: D. Move at different speeds in the column

Chromatography is a laboratory technique used for the separation of mixtures. In the case of ink, chromatography can be employed to separate its components. The separation is based on the ability of the components to Move at different speeds in the column.

In chromatography, a sample is dissolved in a mobile phase (solvent) and then carried by it through a stationary phase. The components of the sample interact differently with the mobile and stationary phases, causing them to move at different rates. This differential movement results in the separation of the components, allowing for their individual identification and analysis.

In the case of ink, which is typically a mixture of various dyes and pigments, chromatography can be used to separate these components. As the ink sample is carried through the stationary phase by the mobile phase, the different components will move at different speeds based on their interactions with the stationary phase. This allows for the visualization and analysis of the individual components present in the ink.

Overall, the ability of the components of ink to move at different speeds in the chromatography column forms the basis for its separation using this technique.
