ISOLATION OF CHLOROPHYLL AND CAROTENOID PIGMENTS FROM SPINACH:
What would happen to the Rf values of the pigments if you were to increase the relative concentration of acetone in the developing solvent ?
I said the Rf values would be higher because Acetone is more polar than hexane ... so the components would move faster across the TLC plate. We used 70%hexane-30% acetone for preparing our development chamber. ... I would like to know if my answer is right and if not what's the right answer please. Thanks
