Chromatography of Food Absorb dyes
The purpose of this research was to employ different inorganic dyes to determine the Rf value. Chromatography is done to look for the presence of your mixture in a substance. From this experiment several dyes had been used including McCormick food coloring, M& M's, Kool-Aid, and the chemical dyes that came with the lab set up.
Experiment and Observation:
From this experiment a 50mL beaker was filled up with luke warm water and a pinch of salt normal water was blended in it and set besides. A line was driven with pencil 1 cm from the bottom with the paper then the line was separated with cross lines 1 . 5cm apart about two bedsheets of chromatography paper. The sections around the first piece of daily news were branded B1, B2, R3, R40, Y5, and Y6 intended for the FD& C meals colors and KG and KS for the grape and blood Kool-Aid. The 2nd sheet was labeled 3rd there’s r, Y, G, B for the food market bought meals dye and MR, MY, MB, MG for the M& M's and UK for the unknown.
For each and every dye examined on the bed sheet of chromatography paper a number of drops with the dye were put in a well of the 24-well plate. A toothpick was dipped in to each of the bore holes and a little dot from the dye was put on the paper in the center of the line. A number of drops of water were added to the two different Kool-Aid's and also to the M& M's. After all the samples were placed on both equally sheets of chromatography daily news they were remaining to dry for a few minutes.
Even though the dye was drying for the paper, it water blend was placed in a petri dish regarding 0. 5cm high. The chromatography newspaper was after that stapled to form a cylinder. The paper was placed up coming to the petri dish to ensure that the water level was under the line that was driven. The newspaper was after that placed in the petri dish making sure not to touch the sides. It absolutely was allowed to take a seat in the salt water for some minutes until the solvent ended traveling the paper. It was then taken out to dry plus the second paper was put in the eluting solvent and...
