This reaction couples a type of toluene sulphonic acid with a different type of naphthalene sulphonic acid. It is necessary for students to mark the solvent front and positions of the dye bands or spots immediately after the strip is removed from the flask. Still, the FAC did suggest the need for more research on developmental neurotoxicity and the ways diets expose children to food dyes. C. Using this hypothesis, predict the relative color intensity that would be produced by methyl orange on cotton, nylon and wool.
Food coloring regulation is just one example of the agency's efforts. 3 The student can collect data to answer a particular scientific question. Sample A has a stronger affinity (attraction) for the eluent (solvent) than the paper, so it traveled farther with the solvent.
