Question

Components of an ink can be separated by:

• A. Chromatography
• B. evaporation
• C. filtration
• D. sublimation

Answer 1

The correct option is A

Chromatography

Chromatography: Chromatography is a technique for the separation of a mixture by passing it in solution or suspension through a medium in which the components move at different rates.

The explanation for the correct answer:

Option A: Chromatography

• Chromatography is a process for separating constituents of a mixture like ink.
• Ink is also a mixture of several dyes and so we can separate those colors through the chromatography process.
• During this process the different mobile components of the mixture travel through the solvent at different speeds, making them separate.

The explanations for the incorrect answers:

Option B: Evaporation

• The process by which water changes from its liquid state to a gaseous state or vapor.
• We cannot separate the component of ink using this method.

Option C: Filtration

• The process of separating solid particles from a liquid by passing through a filter or pores of filter paper is called filtration.
• We cannot separate the component of ink using this method.

Option D: Sublimation

• The phenomenon by which a solid substance gets converted into a gaseous state directly, without passing through the liquid state is known as sublimation.

• We cannot separate the component of ink using this method.

Conclusion:

Therefore, the right answer is option A chromatography.
