What is a conclusion for candy chromatography?

Answer 1

Paper chromatography is an important separation technique that depends upon differences in how strongly the dyes are adsorbed onto the paper (stationary phase) and how soluble the dyes are in the developing solvent (mobile phase). In paper chromatography, a small amount of the mixture to be separated is placed close to the edge of a piece of paper. The edge of the paper is then immersed in a developing solution. As the developing solution ascends up the paper by capillary action, the. components of the sample are carried along at different rates. To prevent evaporation of the developing solution, this process is carried out in a closed container. Each component of the mixture will move a definite distance on the paper in proportion to the distance that the solvent moves. This ratio, Hf = distance component moves/distance solution moves, can be calculated for each component to aid In identification. Hf values are dependent upon the paper, the developing solution, and the amount of sample used. Candies, such as Mix's or Skittles, contain FD&C dyes, sugar, and other organic and Inorganic substances In their coatings. If the coating is dissolved in an acidic solution, the FD&C dyes can be adsorbed from the solution by wool. The dyes can be released from the wool in an alkaline environment. Thus the dyes can be separated from other substances in the coatings. This simplified equation represents the equilibrium involved: Wool + Dye + H+ <====> Dyed Wool+ A solution of ammonia can be used to supply sufficient OH- to reduce the concentration of the H+ and shift the equilibrium to the left releasing the dyes.

Answer 2

When you are doing a hypothesis you always have to think about your problem. You probably think there is no problem when your doing candy chromatography but there is!! Your hypothesis can be about which color will rise first or how many pigments each color is made out of.

Tip: Do not look at the results before you write a hypothesis because its what you think will happen.

Answer 3

You will get different colours in the filter paper :)

Answer 4

A single colured candy is composed of many colours.

Answer 5

The research on candy chromatography is doing the research and writing down what you get out of the experiment

Answer 6

i need a answer too
