Question:
What factors cause pigments to separate during paper chromatography
Answer:
polarity of the pigments more polar greater attraction to the paper making it harder for those molecules to be pulled up the paper so they separate from less polar molecules that are not as attracted to the papersolubility of pigment in solvent used greater solubility more easily carried by the solvent as it travels up the paper NOTE This is why different solvents wouldproduce different patterns of pigments on the paper
