Answer:

ion travelled : 2.00cm -0.40cm

= 1.6cm

∴ Rf = 1.6/2.0

= 0.80

Explanation:

Retention factor is the ratio of distance travelled by solute divided by distance travelled by solvent.

since you given distance travelled by solvent then the distance required by solute is need in this case the ion.
