Coke and mentos chemical reaction
A Diet Coke and Mentos eruption is a reaction between the carbonated beverage Diet Coke The eruption is caused by a physical reaction, rather than any chemical reaction. The addition of the Mentos leads to the rapid nucleation of carbon.and
Drop a few Mentos into a two-liter bottle of soda, and a geyser of foam erupts rapidly, sometimes reaching heights of 15 feet or more. First made famous by chemistry teacher Lee Marek on the Letterman show in , the phenomena sparked hundreds of homed videos and an episode of Discovery Channel's "Mythbusters. The bubbles in a bottle of soda are caused by molecules of dissolved carbon dioxide. Generally, water molecules like to stay next to each other, which prevents any dissolved gases from collecting. However, when offered a surface, called a nucleation site, dissolved gases such as carbon dioxide can gather, eventually forming a bubble.
The basic science of the Coke and Mentos reaction is fairly straightforward. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve. Your average two litre bottle of Coke will contain about fifteen grams of dissolved carbon dioxide. When you open a bottle of a carbonated drink, you release the pressure. These pits, peaks, and craters are referred to as nucleation sites. Science teachers are well aware that some types of carbonated drinks work better than others for this demonstration; for example, Diet Coke usually gives a higher fountain than regular Coke.
Key concepts Chemistry Physics Materials science Carbonation Physical reactions Explosions Introduction Have you ever seen the Diet Coke and Mentos experiment that is all over the Internet and wondered what makes the reaction work? You might think that there is some ingredient in a Mentos candy that causes a chemical reaction with the soda pop, like the way baking soda reacts with vinegar. 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! Instead it is a physical reaction. That means that all of the pieces of the reaction are there, but that they are simply rearranged.
A Diet Coke and Mentos eruption also known as a soda geyser is a reaction between the carbonated beverage Diet Coke and Mentos mints that causes the beverage to spray out of its container. The tubes of candies were threaded onto a pipe cleaner and dropped into the soft drink to create a geyser. At the end of the s, the manufacturer of Wintergreen Lifesavers increased the size of the mints and they no longer fit in the mouth of soda bottles. Science teachers found that Mint Mentos candies had the same effect when dropped into a bottle of any carbonated soft drink. The experiment became a subject of the television show MythBusters in
How Does This Work? That creates so much pressure that the soda goes flying. We then built nozzles that make the opening smaller and that makes the geysers go even higher. So what is nucleation about and why do Mentos release all this pressure so spectacularly? Read on . Their explanation is this process called nucleation. All the carbon dioxide in the soda all that fizz is squeezed into the liquid and looking for a way out.
Diet Coke and Mentos eruption
There have been several disputed theories as to why Diet Coke erupts in a geyser when introduced to Mentos, but the most prominent and most supported are that of nucleation and a chemical reaction between the soda and Mentos. Many notable sources including Scientific American, American Chemical Society, and Discover Chanel's Mythbusters have created content in regards to this reaction with varying beliefs and assumptions.
