Solution
Correct Answer:
4.8 cm
Rf is defined as distance traveled by solute divided by distance traveled by solvent front. Therefore, distance by solute = 0.60 x 8.0 cm = 4.8 cm. This value must be less than solvent-front distance, which is satisfied.
This medium difficulty chemistry question is from the chapter principles related to practical chemistry, covering the topic of paper chromatography. It appeared in the 2025 exam.
