Answer: Substance A will travel further at the end of the experiment and also it will have larger Rf value compared to substance B.
Explanation:
The affinity of substance towards the stationary or mobile phase means how much the substance binds to a phase. Because component B has greater affinity for the stationary phase, it binds more to stationary phase; while component A binds more to a mobile phase. Due to differences in their affinity, component A and B can be separated using chromatography. Stationary phase, as its name says, stays fixed, while the mobile phase is moving. Together with the mobile phase travels component A because of its greater affinity, while component B stays fixed due to its greater affinity for the stationary phase. In conclusion , substance A will travel further at the end of the experiment.
Rf value (Retention Factor) can be defined as the ratio of the distance traveled by a substance in the mobile phase (solute) compared with the distance traveled by the front of the mobile phase itself (solvent front).
Rf = Migration distance of substance / Migration distance of solvent front
Because the solvent front is always larger from the distance traveled by the solute, Rf values are always between 0 and 1. The farther a compound traveled, the larger its Rf value will be. In this example, substance A will have larger Rf value compared to substance B.
