Which of the following mixtures is suitable for chromatography?

Chromatography is an analytical technique used to separate and analyze components within a mixture. It relies on the differential distribution of substances between a stationary phase and a mobile phase.

The choice of inks, dyes, and coloring agents as a suitable mixture for chromatography is ideal because these substances are typically pigments or compounds that can dissolve or disperse in a solvent, making it possible to move them through a stationary phase, such as paper or a chromatography column. This allows for the effective separation based on their chemical properties, such as polarity and size.

In addition to being suitable for separation, inks and dyes often have distinct colors, which enables easy visual identification during and after the chromatography process. This makes it not only practical but also widely applicable in various fields, such as chemistry, biochemistry, and material science.

Other mixtures, like gases and vapors, are generally not suitable because the chromatography technique often requires a liquid or solid stationary phase, and gases do not interact with the stationary phase in the same way. Solid crystals might not dissolve adequately to allow for separation in the liquid phase. Emulsions and gels can be complex mixtures but may not provide a clear and effective separation due to their heterogeneous nature and the interactions between phases.

Thus, inks, dyes,
