The food dyes contain propylene glycol in addition to the dyes and water. The candy shells contain sucrose, corn syrup, corn starch and gum acacia. Do you think this affects the movement of the dyes on the chromatography paper?

do an experiment: Add more corn syrup to the dyes, and see if there is a change. YOu can do the same with the rest of the chems.

To determine whether the additional ingredients in the food dyes and candy shells affect the movement of the dyes on the chromatography paper, we need to understand how chromatography works.

Chromatography is a technique used to separate and analyze mixtures. In this particular case, we are talking about paper or thin-layer chromatography (TLC), where a stationary phase (the chromatography paper) and a mobile phase (the solvent) are used to separate and identify the components of a mixture.

In TLC, the stationary phase (chromatography paper) contains small fibers that act as the adsorbent material. When the mobile phase (solvent) is added to the paper, it moves through the small fibers by capillary action. The different components in the mixture will interact differently with the adsorbent material and the solvent, resulting in different rates of movement.

Now, getting back to your question, whether the additional ingredients in the food dyes and candy shells affect the movement of dyes on the chromatography paper depends on their chemical properties and interactions with the adsorbent material and solvent.

Propylene glycol, which is found in some food dyes, is a common food additive that is used as a solvent. It is generally polar and can interact with the adsorbent material and solvent in a similar way to other components. Therefore, its presence in the food dyes is unlikely to significantly affect the movement of the dyes on the chromatography paper.

Regarding the candy shell ingredients, sucrose, corn syrup, corn starch, and gum acacia are all carbohydrates. These compounds can be polar or even mildly polar, meaning they may interact with the adsorbent material and solvent. However, since they are present in the candy shell and not directly in the food dyes, their influence on the dye's movement would likely be minimal.

In conclusion, while the additional ingredients in the food dyes and candy shells may have some interaction with the adsorbent material and solvent, it is unlikely that they would significantly affect the movement of the dyes on the chromatography paper. To confirm this, you could perform a chromatography experiment using different samples of food dyes with and without the additional ingredients and compare their movement on the chromatography paper.
