Paper chromatography is a simple but reliable method forseparating a mixture into its constituent substances. Youhave a mixture of two vegetable dyes, one red and oneblue, that you are trying to separate. You try two differentchromatography procedures and achieve the separationsshown in the figure. Which procedure worked better? Canyou suggest a method to quantify how good or poor theseparation was?
