Chapter 6 Laboratory: Separating Mixtures 115q: 8 Two of the components of an analyte mixture have Rf values of 0.25 and 0.83. Which of these components is more soluble
in the mobile phase? How do you know?
q: 9 You have run a chromatogram on an analyte mixture in which one of the components remains unidentified. You have
calculated an Rf value for that unknown analyte and are comparing that value against a table of known Rf values. In addition to
the Rf value itself, what other information do you need about the known value to make your comparison valid? Why do you need
this additional information?
