Question

The separation of two coloured substances was done by paper chromatography. The distance travelled by solvent front, substance A and substance B from the base line are 3.25 cm, 2.08 cm and 1.05 cm, respectively. The ratio of  values of A to B is .

Canvas Classes · Accepted Answer

Step 1: Recall the  Formula

Step 2: Read the Given Data

- Distance moved by solvent front = 3.25 cm
- Distance moved by substance A = 2.08 cm
- Distance moved by substance B = 1.05 cm

Step 3: Calculate  Values

Step 4: Calculate the Ratio

Simplifying:

Exact ratio:

As a simple ratio: approximately 2 : 1

Step 5: Interpretation

- Substance A has higher  (0.64) → less polar
- Substance B has lower  (0.32) → more polar (stronger interaction with stationary water phase)
