Question

which variables have a direct effect on movement in chromatography? check all that apply.
check all that apply
color of pigment
solubility of pigment
size of pigment
fluorescence of pigment

Explanation:

Chromatography separates substances based on their interaction with the mobile and stationary phases. Solubility affects how well a pigment dissolves in the mobile phase (e.g., a solvent), which directly influences its movement. Smaller - sized pigments can move more easily through the pores or spaces in the stationary phase (e.g., paper in paper chromatography) compared to larger - sized ones. Color and fluorescence are properties related to how the pigment absorbs or emits light, not directly related to its movement in the chromatographic process.

Answer:

Solubility of pigment, Size of pigment
