Experiment 3 Pre-Lab Questions 1. Define Ry value. The votio of +re distance spot has moved to the distance the Solent has maved 2. A student performs this experi folowing data from the completed 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 4.10 cm Calculate the Rrvalues for each component. RE of A: 5.80/130-0.19S cm RE o8 2.45/1.30 o.336 cm ReFC-u.io/7-3so. 56 acm 3. The unknown mixture spotted on the chromatogram described above produces 2 spots: one blue with an Rrvalue of 0.788 and one tan with an Ry value of 0.568. Which com- ponents were present in the unknown mixture? Calculate the distance in cm moved by each components of the unknown mixture. Account for any difference between these values and those observed for the known components.

Explanation / Answer

your answer for 1 and 2 are correct.

3) componud A(Rf=0.795) and compound C (Rf=0.562) are present in the mixture

distance travelled by A for solvent run of 7.3 cm it will be 5.75 cm and that for C will be 4.102 cm
