40 ANAL0492: Separating and Identifying Food Dyes by Paper Chromatography 4. A student tested water with 2% NaCl as a possible solvent for the separation of a mixture that could contain onc or morc of the following: G3, Y5, R3, and B1. He obtaincd the chromatogram of the individual dyes and the mixture shown below. solvent front G3 Y5 R3 B1 Mix origin line (a) Measure the distance the solvent front moved. solvent front (b) Measure the distance each spot moved. G3 Y5 R3 B1 (c) Calculate the Rf for each component. G3 Y5 R3 B1 (d) Which dye(s) can the student say, with certainty, is/are present in the mixture? (e) Is water with 2% NaCl a good choice for the resolution of the mixture? Briefly explain.
