Kit Thin Layer Chromatography

Not yet rated

Commercial food colors may contain more than meets the eye. Students will perform thin layer chromatography, a highly effective separation procedure, on four different food colors to determine if there may be more in each color than visual appearance would lead them to believe. Each group will perform the chromatography procedure in one of three different solvents and compare their results to other student groups, allowing students to reach conclusions regarding the solubility of each food dye in different solvents. The kit contains enough materials for 15 groups. Teacher’s Manual and Student Study Guide copymasters are included.
