What Is The Mentos And Coke Reaction

What Is The Mentos And Coke Reaction. These microscopic irregularities on the mentos’ surface serve as nucleation sites where carbon dioxide bubbles form. Mentos mints are covered with many very tiny pores or nucleation sites.

But the amazing eruption that takes place when mentos are dropped into diet coke or other brands of diet soda pop is not a chemical reaction at all! Why is diet coke and mentos a physical reaction? All the gas is released and literally pushes all the liquid up and out of the bottle.

The Reaction Happens Fast, So Don’t Have Your Face Over The Bottle.


Mentos mints are covered with many very tiny pores or nucleation sites. Slowly and carefully open a new bottle of diet coke. We report on an experimental study.

As The Mentos Candy Sinks In The Bottle, The Candy Causes The Production Of More And More Carbon Dioxide Bubbles, And The Rising Bubbles React With Carbon Dioxide That Is Still Dissolved In The Soda To Cause More Carbon Dioxide To Be Freed And Create Even More Bubbles, Resulting In The Eruption.


The basic explanation is that the carbon dioxide gas inside the diet coke is being released. Well, you would probably find better explanations on the web. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve.

Coke Is Carbonated, Which Means It Has So Much Carbon Dioxide Mixed Into It That The Co2 Will Find Any Excuse To Escape.


However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. The carbon dioxide gas coming out of solution), the reaction is a physical reaction. As it sinks, the mentos produces more bubbles, which react with carbon dioxide in the soda, rewarding you with a diet coke geyser.

The Chemical Reactions Involved In Dropping Mentos Candies Into A Bottle Of Diet Coke Make Quite The Spectacle!


Don’t open the soft drink bottle until you’re ready to start the experiment, otherwise all the fizz will dissipate. Soda geysters, which can reach as high as ten meters, were a popular subject for viral videos in the early 2000's, but the science behind the spectacle remained a mystery until 2008. The reaction has been performed numerous times on television and the internet, but has not been systematically studied.

The Diet Coke And Mentos Reaction Is A Fun Demonstration In Chemistry And Physics Classes Of Many Important Concepts In Thermodynamics, Fluid Dynamics, Surface Science, And The Physics Of Explosions.


You can also increase the effect by adding more surfactants to the soda before you add the mentos, like adding a mixture of dishwasher soap. As to why diet sodas like diet coke produce such a bigger reaction, it’s because aspartame lowers the surface tension of the liquid much more than sugar or corn syrup will. Initially water molecules are trapping the carbon dioxide.
