Comparison Of Diet And Soda Reaction

Decent Essays
Mentos and soda reaction has been a fun experiment done by people across the world.
Yes, it is a easy project you can do. You can do it by yourself or with friends but, do you know the science behind it? Do you know if it is a physical reaction or chemical reaction? The reaction of soda and Mentos causes a fun explosive outcome but, why? When you drop the the Mentos in the diet soda it causes carbon dioxide bubbles to form really fast. Then the bubbles form until it forms a geyser. Not only the bubbles form the sticky and foamy reaction. The ingredients from the Mentos mixed with the sugar from the diet soda causes the soda too have a lower surface tension. It is hard for bubbles to form at a high surface tension ( “Why Do Diet Coke

According to Mental Floss, this is their explanation of why diet soda works better. “Diet sodas produce a bigger reaction than non-diet sodas because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. You can also increase the effect by adding more surfactants to the soda when you add the Mentos, like adding a mixture of dishwasher soap and water”(“Why Do Diet Coke and Mentos React?” Mental Floss). Why is it a Physical reaction? It is a Physical reaction because of Nucleation. What causes the reaction of soda and Mentos slow or stops the reaction? To slow down the experiment a person would have to make sure that the carbon dioxide must escape from the soda. If that person does not have carbon dioxide in the soda the Mentos will not react to cause a fun and exciting Physical reaction( “Mentos and Diet Coke Experiment | Science Project” ). What is Nucleation? Nucleation is a form of crystallization.( The Editors of Encyclopædia Britannica. “Nucleation”). In conclusion the soda and Mentos reaction is fun, easy, and cheap.It is a physical reaction and it is because of nucleation. Remember when doing the experiment think about what is occurring during the
