Question

Name the method used for the separation of the mixture of dye from black ink.

Answer 1

Answer:

Separation of mixtures.

• The process of separation of different constituents of a mixture using physical methods is known as the separation of mixtures.

The separation of the mixture of dye from black ink:

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.

• Ink is also a mixture of several dyes and so we can separate those colours through the chromatography process.
• The different mobile components of the mixture travel through the solvent at different speeds, making them separate.
• So, the black ink gets separated from the dyes of ink by chromatography.

Conclusion:
Therefore, chromatography is the method used for the separation of the mixture of dye from black ink.
