Question

according to this chromatography strip, which dye color is most similar to the mobile phase (the rising water)? options: the green dye, the blue dye, the red dye, the yellow dye

Explanation:

In paper chromatography, dyes with the greatest similarity to the mobile phase (water, polar) travel the farthest up the stationary phase (paper). The red dye has moved the highest distance on the strip, meaning it interacts most strongly with the mobile water phase and is most similar to it.

Answer:

the red dye
