The best technique for separating the components of a dye is

A. chromatography

B. distillation

C. evaporation

D. filtration

✅ Answer: A. chromatography

Let’s carefully analyze this question: “The best technique for separating the components of a dye is …”

1. Understand the mixture:

   • A dye is usually a mixture of colored substances, often dissolved in a solvent.

   • The goal is to separate its different components, not just remove the solvent.

2. Check the options:

   • A. Chromatography → This is specifically used to separate components of a mixture based on their solubility and movement on a medium. ✔

   • B. Distillation → Separates substances based on boiling points, not suitable for separating different dye components.

   • C. Evaporation → Removes the solvent, leaving residue; doesn’t separate components.

   • D. Filtration → Separates solids from liquids, not components of a solution.

✅ Answer: A. chromatography
