2 Dye A has a R value of 085 while a R value of 043 was repo

2) Dye A has a R value of 0.85 while a R value of 0.43 was reported for dye B. Which dye spent the most time in the stationary phase?

Solution

Rf= distance traveled by the dye/ distance traveled by mobile phase

So less the value of Rf more time that the dye present in stationary phase.

In the above problem the Rf of dye B is less so it will spent more time in stationary phase.
