Learning outcomes
Candidates should be able to:

1. describe and understand the terms
   (a) stationary phase, for example aluminium oxide (on a solid support)
   (b) mobile phase; a polar or non-polar solvent
   © Rf value
   (d) solvent front and baseline

2. interpret Rf values

3. explain the differences in Rf values in terms of interaction with the stationary phase and of relative solubility in the mobile phase
