Candy Chromatography Essay Example
Candy Chromatography: What makes those colors?

The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture, based on molecular size or other chemical properties. It can also be used to identify chemicals, for example crime scene samples like blood, drugs, or explosive residue. Highly accurate chromatographic methods are used for process monitoring, for example to assure that a pharmaceutical manufacturing process is producing the desired drug compound in pure form.With colored mixtures in paper chromatography, you can see the components separate out on the paper. A mixture of various components enters a chromatography process, and the different components are flushed through the system at different rates.
Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for further use. Analytical chromatography is done normally with smaller amounts of material and is for measuring the relative proportions of analytes in a mixture. I think in order to make the candie different colors that they put drops of many different colors into the product to make one definite color. This is my hypothesis because in order to do my project I have to find which colors are used to make a candy one color, so that must mean that the candies have more than one color dye in it. I've read that in order to perform chromatography, I'm going to separate different mixtures. This is an important experiment because when people are eating Skittles some probably wonder “How do they make this Skittle red?”. So now I can figure out with color dyes they used to make a specific color for the Skittle.
I think someone would want to do this experiment because first of all it's fun, but you're learning at the same

    The first step was to prepare the two filter paper for the experiment so you can measure the different columns at the end of the experiment. For that to happen you have to draw a horizontal line with a pencil. The line has to be 1cm above the bottom. After that you draw nine cross lines along the horizontal line with a space between each cross line of 1.5cm. Now you have to mark each area with a shortcut of the substance you are going to put on the horizontal line. The next step is to prepare each of your substances in the 24-well plate. Once you put all the substances in the well plate and dissolved the color from the M&Ms and Kool Aid with some drops of water, you dip a clean toothpick in the dye. You mark carefully a little point on the horizontal in the center of the section you marked with the substance and make sure the point is not too big because otherwise the experiment won’t work as good. The filter paper needs to dry for a few minutes before you form both to a cylinder and staple it so it stays a cylinder. Before you can keep going with the experiment you have to take a 50ml plastic beaker and fill that one with 50ml distilled water, solve a pinch salt in the water and stir until you can’t see crystals anymore. Pour a little bit of that solution in a petri dish but make sure it will be below the horizontal line you draw on the filter paper. Set…

    In order to experiment with distinct components of a mixture, they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase, which the TLC plates as well as a mobile phase, which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result, nonpolar substances travel further than polar substances in this process. The separation of a mixture into its components by TLC transpires because the distinctive components of a mixture interact to different extents with the stationary and mobile phases.…

    To complete this lab, I first mixed the solvent solution consisting of the proper ratio of water, salt, and isopropyl alcohol in a Pyrex measuring cup. I then prepared my chromatography papers for 2 trials by drawing, with a pencil, the appropriate lines and labels. Using a toothpick, I added the color to the paper, and then repeated until the color was strong. I repeated this step several more times for the M&Ms as the color solution was not as strong as the food dyes. After the dyes were dry, I rolled the paper and added it to the pie plate, which contained a small amount of the prepared solvent. I then waited for the solution to…

    Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble inks. W put three dots of water soluble ink on a piece of filter paper and four dots of acetone soluble ink at the other end. We then put the end of the filter paper in a small amount of distilled water in a beaker. The filter paper absorbed the water and the ink slowly spread to the top of the paper. We repeated these steps for both the water soluble and acetone soluble ink but when we did the acetone soluble ink, we placed the filter paper in an acetone-water mixture instead of just distilled water. We then recorded our results which showed that water soluble inks traveled farther than the acetone soluble inks. The results of our experiment showed how each different color of water soluble inks traveled farther than any of the acetone soluble inks.…

    Candy Chromatography is the method of analysis of separating and comparing dyes used in candies and food coloring. It is also a proven method to analyze candy and its complex structure, without having to taste it. These complex mixtures can be separated back into pure substances. To find out the ingredients of a favorite candy, chromatography would help to define every ingredient found in the candy sample. The word chromatography is derived from the two Greek words, “Chroma” meaning color and “graphic” meaning to write. Paper chromatography is the best method of separation used in candy chromatography. Paper chromatography is a technique that involves placing a small dot or line of sample solution onto a strip of chromatography paper.. The paper is placed in a jar containing a shallow layer of solvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent. This paper is made of cellulose, a polar substance, and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far.…

    (As The Editors Of Encyclopædia Britannica say “Paper chromatography, technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. The method consists of applying the test solution or sample as a spot near one corner of a sheet of filter paper. The paper is initially impregnated with some suitable solvent to create a stationary liquid phase. An edge of the paper close to the spot is then immersed in another solvent in which the components of the mixture are soluble in varying degrees. The solvent penetrates the paper by capillary action and, in passing over the sample spot, carries along with it the various components of the sample.”) they explain what and how paper chromatography is used for. They all have to do with colors. Having to do with finding the real dyes in colors. (As Science Buddies explain “What color is black ink? Sometimes things are not just what we think they are. Often things can be broken down into component parts. One way to find out it to use a common chemistry technique called chromatography.”) This quote explains that there can be many object in just one object, just like paper chromatography. The paper chromatography experiment it tested to see what kind of dyes are just in one…

    Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a, chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility, which results in different distance traveled up the paper. Beta carotene is non-polar so it travels the highest distance, followed by chlorophyll a. Chlorophyll b is the most polar; therefore, it travels the shortest distance. The separated pigments on the chromatography paper can be eluted in acetone and absorbance spectrum is determined using spectrophotometer. Spectrophotometer produces a graph of the absorbance spectrum which shows the wavelengths (in nm) that are absorbed by the pigment and that are reflected. The reflected wavelength of chlorophylls a and b reflect the wavelengths of l light that are associated with green, which gives them their color. Beta carotene reflects the wavelengths that are associated with orange color, and that explains its color.…
