The scope of this paper is to explain the reaction that takes place when Mentos are dropped into Diet Coke. This experiment is used frequently because of what happens when the candy meets the soda. A geyser is formed that shoots out of the bottle that resembles a volcanic eruption. Due to the similarity, it is also used for volcano projects. Depending on the alterations to the Mentos and/or Diet Coke, the geyser can either go much higher or much lower than normal.
This reaction has produced much confusion among people about whether it is a physical or chemical reaction. It is a physical reaction because the substances remained the same, the reaction did not form a new substance. (Coffey) What creates the physical reaction is water molecules that go into the pores on the Mentos. The rough surface of Mentos allow this to happen. The water molecules grow to create carbon dioxide bubbles on the outside of the candy. The Mentos gain buoyancy, which means they rise to the surface of the soda. After this occurs, there is increased bubble formation, resulting in the liquid turning to foam and shooting out of the bottle. Bubble formation is also increased by the gum arabic and gelatin in the Mentos combining with the potassium benzoate, sugar, and aspartame in the Diet Coke. (Hiskey, Mental Floss)
As stated above, there are alterations that speed the reaction. These include decreasing the surface tension of the Diet Coke, performing an acid-base reaction, and warming the Diet Coke.
Observations: During the experiment, bubbles were present from the water in the electric water baths that were set at temperatures of 50 degrees Celsius and 60 degrees Celsius. This is because the water has passed its boiling point and began to boil. The glucose powder had a white color. The yeast powder had a mild yellow color. When the glucose solution was mixed with water, it gave a clear color. When glucose solution was mixed with the yeast, it produced a murky yellow color. Bubbles also arose when CO2 was being lost in the experiment under each desired temperature.
There is a lot of High Fructose Corn Syrup, the sugar of choice, in regular sodas. People started finding out about how bad sugar is for them and how much sugar was really in their favorite every day drink. Everyone started turning against all of the soda companies and they had no choice but to come up with an alternative. So, instead of using natural sugar or High Fructose Corn Syrup in sodas, scientists invented artificial sweeteners, a way to keep the soda sweet yet contain no sugar. Artificial sweeteners like Aspartame that are added to diet soda are actually worse for us than the sugar that is in regular soda. This was proven by an Osteopathic Physician from the American Colledge of Nutrition who states, "While many of the artificial sweeteners have reportedly similar side effects, aspartame accounts for over 75 percent of the adverse reactions to food additives reported to the FDA" (Mercola).
The diet coke and Mentos experiment has been a favorite of amateur scientists, but how does it work? There have been debates, and scientists have concluded that the diet coke and Mentos is a physical reaction, called nucleation. Nucleation sites are areas that have high surface with low volume. Such places can be your fingerprint, scratches on glass, specks of dust, or even Mentos candy (Eepy Bird). Mentos candies have a pitted surface that’s rough when looked at through a microscope, therefore creating a wonderful place for nucleation to occur. Water molecules like to be next to other water molecules, so if you drop something into the soda, like Mentos, it acts as a site for growth of bubbles. Mentos have a high
The purpose of this experiment was to see if altering the ingredients of a bath bomb affected the effervescent when placed in water. When a bath bomb is submerged in water the ingredients caused it to fizz, releasing a scent and changing the color of the water. This bath bomb experiment requires two recipes, the first recipe which was labelled as “normal”, contained less cornstarch than the other recipe. In addition to the “normal” recipe, the other recipe was labelled “extra” because it contains more cornstarch. During this process, by adding or subtracting ingredients the eversences of the bath bomb changed. If more cornstarch is added to the recipe, the bath bomb will not fizz as much when placed in water. This is caused by the cornstarch,
If 10.0g of solid baking soda is poured into 30 mL of citric acid, then a reaction will occur and an increase in temperature will be observed. Whereas, if a piece of magnesium metal is added to 30 mL of Hydrochloric Acid, then a reaction will occur and an increase in temperature will be observable. For Part 3 of the experiment, if 50 mL of tap water is placed in a can 2.5 cm inches above a burning marshmallow, then through the process of calorimetry the energy content of the marshmallow should be 5.0kJ/g (the value provided by the United States Department of Agriculture).
For this lab, we brought a empty soda can to school to show how pressure and temperature can affect the structure of the can. To begin the experiment, we needed a empty soda can, water and ice in a small plastic tub, and a hot plate. First, we added about a tablespoon of water to the empty soda can. Second, we put the soda can on the hot plate and waited until the water was brought to a boil. Then we used beaker tongs to carry the hot soda can and flipped it over into the container of water and ice. Once the can touched the water, the can made a loud crushing sound and the can crippled inward.
Which brand of soda tested spews the most liquid when three Mentos are doped into a 2-liter of each brand? We know that the reaction between Mentos and soda is an explosion, but what we are trying to figure out is which brand causes the biggest reaction.
Well, as you probably already know, all beverages have different tastes and looks. But do all of them have the same or different reactions? Although beverages is an entity people drink on a daily basis. We don't know if it will have a reaction. This paper will examine, identifying beverages with its different reactions, the mass of a bottle and affect how the reactions are, and lastly, how it is manufactured. The goal of this paper is to prove that some beverages will have or will not have a reaction.
Why do Diet Coke & Mentos and Coke Zero & Mentos create such exciting geysers?
I am researching,”Does the type of soda effect the amount of fizz that comes out of a can with mentos” . According to “ Diet coke and mentos; Why the reaction” it says that the Ingredients in the mentos effect the reaction because inside the mentos it has Potassium Benzoate and aspartame. Mentos have Potassium Benzoate and Aspartame to make the soda fizz and the carbon inside the soda makes the fizz pack together and it tries escape the can. The bubbles inside the soda is carbon dioxide and when the carbon dioxide mixes with the mentos it causes the fizz to mount up and it escapes the can. The Potassium Benzoate and Aspartame reduces the amount of work required to form bubbles in the carbonated soda.
There are many ingredients in soda that is bad for you.What is soda made of? Soda is carbonated water that is flavored and sweetened with sugar. Soda is basically made of carbonated water, sweeteners, phosphoric and citric acid, caffeine, and natural flavors. The natural flavors added are from fruits, vegetables, nuts, leaves, herbs, and spices. Phosphoric acid is purposely added to soft drinks because it gives them a sharper and tangier flavor. Citric acid and phosphoric acid can not only prevent spoilage, but it also can weaken the bones. In order for me to continue the experiment, I
After completing the experiment, I accept and support my hypothesis which was that 3 Mentos would create the tallest soda geyser. The average height of 1 Mento was 24.7 inches, 2 Mentos was 51.7 inches, and 3 Mentos created the tallest geyser averaging at 58.7 inches. It is clear that the 3 mento geyser is the tallest geyser due to the greater amount of Mentos. In this experiment there were many sources of error. The first one was that the experiment was being done on a uneven surfaces causing the geysers to shoot left or right instead of straight up causing the geysers to not reach their true height. Another error was that when dropping in the Mentos, they were not evenly spaced times causing different reactions and different heights. An additional
Soda goes back to ancient times when ancient Greeks and Romans would use mineral water because of its medicinal properties. Soon mineral water was turned into flavored soda water, and gained popularity not only for medicinal benefits but for the refreshing taste it has as well. In the late 1800’s a Chemist by the name of Constantin Fahlberg failed to wash his hands after working in the lab. While he was eating his dinner, he discovered that everything he touched tasted sweet. The next day he went around the lab and tasted various beakers and evaporating dish in search of the source of the sweet taste. In an overheated beaker, he discovered that “o-sulfobenzoic acid had reacted with phosphorus (V) chloride and ammonia,
You have probably seen the coke and Mentos experiments on the internet and wondered “what causes for the explosion to happen?” You might think that Mentos has something in it that might cause the explosion, but it actually has a lot of sugar on it, with a very rough surface (microscopically). Because of this It give a Mentos plenty of nucleation sites, which means, that the bubbles, or carbonation, has something to attach. Though one might think the explosion from a Mentos dropped into a soda is a chemical reaction but it is actually a physical reaction meaning that all the elements are all there.
After I watched several videos on this specific reaction between molten potassium chlorate and gummy bears, I became fascinated by the reaction that occurred. When I saw the gummy bear come in contact with the molten potassium chlorate I predicted that it was either going to cause a flame or explode. Luckily I was correct a flame appeared. At this point I knew I wanted to do this as my chemistry project, except on mine I'm going to try several different sugar candies like jolly ranchers, sour worms, lifesavers and gummy bears to see if different candies react better than others.
