Step 1

Rf value can be determined as the distance travelled by the solvent divided by its mobile phase can be shown as:

Rf = distance /mobile phase

Distance travelled by mobile phase = 6.1 cm

Step 2

Distance travelled by Fe3+ = 5.8 cm

Rf value of Fe3+  = 5.8 / 6.1 = 0.95

Step 3

Distance travelled by Co2+ = 5.8 cm

Rf value of Co2+...
