Im sure we are all doing the same chromatograhy lab and I found this site and thought it broke it down very well. It also breaks down solvent and solute just as well =)
I definitely think this is a helpful explanation of Raoult's law- especially for those that are struggling to understand the three types of situations Raoult's law covers: nonvolatile non-ionic solute in a solvent, nonvolatile ionic solute in a solvent, and a mixture of volatile solvents.
