Question

Name Section atography paper is spotted with a solution containing two components X and Y. solubility of X in the eluent is less than that of Y. Which substance wil have the largest Re value The chemical affinity of X for the sorbant is greater than that of Y, and the after ascending paper chromatography has taken place? Explain. 6. Wh y should an unknown be run simultaneously with the knowns, if possible? 7. List two advantages of TLC over paper chromatography. 8. List three factors that can affect the R value of a given component.

Explanation / Answer

1. Substance X will have largest Rf value. Though it has high chemical affinity that makes it more which will move in paper chromatoghaphy slowly but the solubility factor can overcome this factor. Thats why Substance X will move first and will have largest Rf value
