Question

which of the following methods is most appropriate to use to determine the number of different-colored components in a sample of black ink? responses distillation at atmospheric pressure distillation at atmospheric pressure elemental analysis to determine the mass ratio of c:h:n:o elemental analysis to determine the mass ratio of c, to h, to n, to o column chromatography using a nonpolar stationary phase and water as the mobile phase column chromatography using a nonpolar stationary phase and water as the mobile phase paper chromatography using different solvents with a range of polarities as the mobile phase

Answer 1

The answer is paper chromatography using different solvents with a range of polarities as the mobile phase.

Paper chromatography- Low-molecular-mass molecules can be separated using paper chromatography based on how evenly they are distributed in the stationary and mobile phases. Paper chromatography is regarded as a potent analytical technique because of its low cost and the availability of numerous procedures for the separation of chemicals.

A small amount of a sample solution is poured onto a strip of chromatography paper in a paper chromatography experiment. After that, a solvent is used to suspend the chromatography paper. The sample solution's constituent components split out into bands of distinct hue as the solvent goes up the paper.

The speed of the chromatography process is influenced by the solvent's polarity. Therefore, we may conclude that all of the other components in the mixture move more quickly during the chromatography experiment if the solvent's polarity is increased.

Thus, answer is paper chromatography using different solvents with a range of polarities as the mobile phase.
