Experiment C: influence of the nature of the deposition solvent
On a porcelain well plate, deposit a spatula tip of solid ferrocene in 4 wells.
Dissolve the solid with:
- for well P1: dimethylformamide (DMF)
- for well P2: ethyl acetate
- for well P3: petroleum ether (EP) (add the solution from vial 11)
- for well P4: ethanol EtOH
Place these 4 solutions, using capillaries, on the same TLC plate, taking care to finally deposit the solutions from wells P3 and P4.
Immediately place the TLC plate to be eluted in a chamber containing petroleum ether (chamber C2). Leave to elute.
Calculate the corresponding Rf values and conclude.
