Candy Chromatography Lab Report
The purpose of this experiment was to highlight the process of chromatography. But why was candy chosen? Recent studies have found that certain dyes can cause hyperactivity in children and even pose certain serious health risks like cancer and tumors. Some such dyes include Yellow 5, Red 40, and Yellow 6 - dyes that are not only found in many foods but more commonly in widely consumed candies which are not normally noticed by those who eat them. By using chromatography, you can test to find out if your favorite candy contains these harmful dyes. In this lab, our hypothesis was proven for the most part. All primary colors (red, blue, and yellow) had no color change, while secondary colors (black, brown, green, purple) changed colors and had two or more dyes. The only exception to the statement was orange. While there is no orange dye, the dyes for yellow and red are so similar that there would be no change in color. Another possibility is that the dyes were not attracted to the solvent so they did not separate. …show more content…
Secondary colors like green and purple resulted in multiple colors, all of which were primary colors. Predominantly red and yellow dyes were found and those dyes are the most harmful to your health. Another trend was the lack of color change in orange candy. While orange is a secondary color, for some reason no change in color resulted. The separation technique of chromatography was brought up in the first unit in Chemistry class. While it was not mentioned as frequently as filtration and distillation, after doing some research I realized chromatography is much more common. Some questions I had while doing this lab were: Why did orange stay the same color? Would using different solvents result in better data? What was the best technique to put the dye on filter paper? If thin-layer chromatography could be used would it be more
Procion Red Dye Lab Report
1454 Words | 6 PagesFor this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
Corn Syrup Lab Report
137 Words | 1 PagesOf course, the various sources of error have affected the results from this lab. Since the initial mass of eggs used was different for each group, the experimenters had to find the percent change in mass to keep the results constant. To conclude, when the eggs were placed in a corn syrup solution with more solute, their masses steadily decreased. The inside of the eggs have a lower solute concentration than the corn syrup solution outside the cell. Water within the eggs flow outwards through the membrane to the syrup solution, decreasing the solute concentration.

That Sugar Film Analysis
537 Words | 3 PagesFatty liver disease, diabetes, obesity, heart disease and many more are the biggest problem that our world is facing these days and that is proven by more than half of the Australia population are suffering from them. Some experts believed that they came from the food’s fat we consumed, but other experts denied and stated that they were caused by the thing that we can found in almost 80% products which are sold in supermarket, that is sugar. As we know, sugar plays a fundamental and crucial role in every kitchen but actually they are a villain for our body. Damon Gameau, the director of That Sugar Film, was curious and wanted to find an answer from what does sugar actually cause to our body by doing a two months experiment consuming 40 teaspoons
Informative Speech On Food Dyes
1258 Words | 6 PagesI. Artificial dyes are found in a majority of processed foods in America. Most of these synthetic dyes are made of or based off of petroleum, a crude oil. Since these dyes are mainly petroleum based they can cause serious health risks on people, especially those diagnosed with ADHD, attention deficit/hyperactive disorder. Because of these potential dangers, laws dating back to the 19th century have been passed, banning the addition of dyes and other harmful substances to foods. Through the years there have been many debates, laws and protests against food dye and their effects on humans and animals.
Informative Essay On Medical Tattoos
679 Words | 3 PagesThe various colors in a tattoo are made from different mate-rials. For example, the red color comes from mercury, the green from chromium, the yellow from cadmium, and the blue from cobalt. Allergic reactions to red dyes occur more often than allergic rea-ctions to other colors. Allergies are an overreaction of the immune system. An allergic reaction can range from mild and annoying to sudden and life-threatening.

A huge process in this lab was paper chromatography, which was used to isolate food dyes that are found in different drink mixes. The different chromatograms of FD&C dyes were compared to identify which dyes are present in each of the mixes.
Skittles Lab Report
959 Words | 4 PagesSenses: How we Identify Different Flavors of Food Aim: To be able to identify the five different fruit flavors of skittles by using the sense of taste, while the participants of this experiment are blindfolded. Research Question: How are we able to identify the five different fruit flavors of skittles (strawberry, orange, grape, lime, and lemon) by only using our sense of taste? Hypothesis: I believe that the blind fold will make it harder for the participants to determine what fruit flavored skittle they have just ingested. This may also alter their perception of taste.
Research Paper On Dyes
852 Words | 4 PagesA dye is a coloured substance that has an affinity, a bond with a physical surface, to the substrate to which it is being applied. Dyes are usually soluble in water. Dyes are used to change the perceived colour of an object. Dyes consist of 2 main parts: chromohore and auxochrome. Before 1856, all dyes were obtained from natural resources.
The Pros And Cons Of Food Coloring
1148 Words | 5 PagesAccording to the Center for Science in the Public Interest’s (CSPI) study on food colorings, “The three most widely used dyes, Red 40, Yellow 5, and Yellow 6, are contaminated with known carcinogens. Another dye, Red 3, has been acknowledged for years by the Food and Drug Administration to be a carcinogen, yet it is still in the food supply.” A 2007 British study has also found that many of the common food colorings and preservatives like sodium benzoate decreased attention spans and increased hyperactivity in children.
Non Taste Lab Report
532 Words | 3 PagesIntroduction The ability to taste or non-taste PTC was discovered over 80 years ago, more exactly in 1931. A chemist named Arthur Fox accidently released a cloud of a fine crystalline phenylthiocarbamide in a lab. One of his colleagues complained about the bitter taste of the dust while Fox wasn’t able to taste it. Since then it has been scientifically proven that not all human beings can taste the bitterness in Phenylthiocarbamide (PTC) (Macbeth 1997).
Photosynthesis: Chromatography Paper Results Of Spinach Leaves
1800 Words | 8 PagesIt is also Chlorophyll b on the other hand, is an accessory pigment however it also absorbs more red and blue wavelengths and also reflects a green colour. The second hypothesis for the second part to this lab was also proven correct. When the chlorophyll pigment in the test tube was held directly under the light, a florescence of colour was seen. In this experiment a colour of purple/pink was seen, however chlorophyll extract should have shown the colour of red when held directly under light. This means that this lab must have had experimental error.
Lab Report On Acid Base Titration
1346 Words | 6 PagesThrough the titration process, we are able to identify physical changes to the mixture such as the colour change to indicate the end point of the experiment. For example, the colour changes of phenolphthalein from colourless to pink and methyl orange from red to orange and subsequently yellow. Acids produce hydrogen ions and bases produce hydroxide ions. This causes the indicator to change colour due to the colour difference from the undissociate molecules.
