Why Do Diet Coke And Mentos To Create Such Exciting Geysers?

During the immersion of the magnesium metal in the hydrochloric acid solution, white bubbles could be seen escaping the surface of the metal as gas was produced during the reaction. Depending on the temperature of the hydrochloric acid and the overall molar concentration, the rate of reaction differed but the same signs were shown. During the reaction between the magnesium metal and higher concentrations of hydrochloric acid, it was observed that the test tube grew quite warm to the touch. As the immersed magnesium strip sank down, it appeared coated in a layer of white bubbles that fizzed like a carbonated drink. In the lower concentrations of hydrochloric acid, the strip spent some time floating at the surface of the solution in the test tube, later sinking down to the bottom as the

Some colas will explode higher or lower because of the amounts of caffeine, sodium, or sugar. Also how fast the mentos fall into the bottle can affect the height of the geysers. It has been proven that there is a difference

gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the

In this experiment, we tested to see if the temperature of water would increase or decrease when we added different amounts effervescent tablets in the water. We had confidence that as the temperature of the water will decrease as the number of tablets increased.

2. In Part 1, why did you not observe a stream of bubbles coming off the stainless steel screw in the sugar solution?

Though many people will think there is a lot of bad in soda, technically it’s just carbonated water, which is basically “gas that’s called carbon dioxide that has been dissolved under high pressure” (sciencebuddies.org). When one opens a can of soda pop the carbon dioxide in it is released out causing the bubbles in the drink, and the best part for this project is that one can choose their own way to do it, yes they may have to follow what the recipe calls for but they can choose their favorite flavors and their own color for it like if they wanted to they could make a bacon flavored pop but it might not taste the best but the point would be that it would be their own idea.

The reaction you will be investigating is the reaction that occurs when an Alka-Seltzer tablet is placed into a given amount of water. Alka-Seltzer is an over-the-counter antacid and pain relief medication that is dissolved in water before it is ingested. Each tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate. As the tablet dissolves in water, the bicarbonate ions in the tablet react with the hydrogen ions from the acids that are also contained in the tablet. The carbon dioxide gas produced by the reaction is what causes the bubbling that can be observed.

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

A rougher candy surface such as, Mentos, means there are more places for bubbles to grow, or more nucleation sites. (brilliant.org) Surfactants are compounds that lower the surface tension between two liquids. (brilliant.org) Dropping Mentos in Coke is an example of a surfactant. The eruptions happen due to nucleation where the Carbon Dioxide in the soda is drawn to the Mentos. (eepybird.com) The pressure of the bottle is trapping the CO2 inside. The CO2 in the soda reacts to the sugar on the Mentos.

When four paper clips were added to the cup, the water had not even begun to show signs of spilling. By the end of the experiment, the cup of water was able to hold 120 paperclips before the water ran over. As the 119th paperclip was added, we noticed a somewhat large “half bubble” on the surface of the cup. This ‘bubble’ was caused by 3 factors known

From the results that were acquired from mixing the liquid reagents with each powder, it was determined that Unknown Mixture #1 consisted of baking soda and cornstarch. When individually testing the substances from Unknown Mixture #1 with the liquid reagents, a few noticeable reactions occurred. Mixing baking soda with vinegar caused bubbling to occur. This is because a neutralization reaction took place between the two reactants. In this reaction, sodium bicarbonate(baking soda) reacts with vinegar and produces sodium acetate, water, and carbon dioxide(HC2H3O2(aq) + NaHCO3(aq) NaC2H3O2(aq) + H2O(l) + CO2(g) ). The gaseous carbon dioxide most likely tried to escape into the atmosphere and caused the bubbling to occur. Another noticeable reaction

Then the gas starts rising towards the surface and form bubbles from kinetic energy. After reaching the surface these bubbles pop. When the solution remains flat in the bottle is because carbon dioxide molecules do not separate from water. So let's say we open the soda bottle this starts to release the pressure that is inside the soda.

Daniella Reilly ECED 3109 Discrepant Event Assignment Grade Level: 1. Outline of Discrepant Event and Overview of Materials and Procedures This discrepant event will help explain the relationship between temperature and pressure, otherwise known as thermal expansion. Through out the experiment students will focus on the topics of heat, energy, and air pressure. Students will also have the opportunity to explore the differences when a covered empty bottle is placed in hot vs. cold water.

As the water inside the can is heated, we used the tongs to place the soda can upside down in the beaker with cold water. After a loud noise, the can is crushed by the pressure inside the can. As the Can is been heated, the gas particle has

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.
