Question

A student performs this and records the following data from the complted chromatogram.

- the solvent has moved 7.30 cm
- Component A produces a blue spot that has moved 5.80 cm.
- Component B produces a pink spot that has moved 2.45 cm.
- Component C produces a tan spot that has moved 4.10cm.

Calculate the R_{f }values for component.

Step 1

The R_{f} value is the ratio of distance travelled by the sample (b) to the distance travelled by the solvent (c). It is given in equation (1).

Step 2

Use the equation (1) and substitute 5.80 for b and 7.30 for c for component A as shown below.

Step 3

Use the equation (1) and substitute 2.45 for b and...
