What this topic asks you to be able to do
- describe each of the following terms and show that you understand it: (a) stationary phase, e.g. aluminium oxide coating a solid support (b) mobile phase, a solvent that can be either polar or non-polar (c) Rf value (d) baseline and solvent front
- interpret Rf values
- account for why Rf values differ, using the substance's interaction with the stationary phase and its relative solubility in the mobile phase
