Spot this mixture onto the line as well. Lay the chromatography paper on a paper towel and immediately mark the solvent front with a pencil. Tentative identification of the components can be achieved by comparing the unknown mixture a carefully prepared known mixture: if a known component has the same retention time as an unknown component under the same conditions, it is probable—but not conclusive—that the two components are the same.
The different metal-ion solubilities are probably due to the formation of various compounds with the chloride ion and their varying ability to dissolve in the organic solvent. Wear disposable gloves to touch your chromatogram after the elution occurs and for the remainder of the experiment.
A diagram showing how to prepare the paper is shown below.
In the diagram, component A moves faster than component B; thus component B is retained on the column for a longer time than component A. It will take about minutes for the solvent front to reach the finish line.
Figure 1 shows a beaker containing mobile phase and a prepared paper stationary phase. Dispose of the gloves and chromatogram in the specified waste container after the experiment is finished.
