Question: Which equation is used to calculate the Rf value in chromatography?

Options:

A) $Rf = \frac{\text{Distance traveled by solute}}{\text{Distance traveled by solvent}}$

B) $Rf = \frac{\text{Distance traveled by solvent}}{\text{Distance traveled by solute}}$

C) $Rf = \text{Distance traveled by solute} \times \text{Distance traveled by solvent}$

D) $Rf = \text{Distance traveled by solute} - \text{Distance traveled by solvent}$

Show Answer

Answer: a

Explanation:

A) Correct. This is the correct equation for calculating the Rf value.

B) Incorrect. This is the inverse of the correct equation.

C) Incorrect. Multiplication is not used in calculating Rf.
