Chemsitry of diet coke and mentos
Can you please explain in simple terms how or why this reaction occurs. The startling reaction between Diet Coke and Mentos sweets, made famous in thousands of YouTube videos, finally has a scientific explanation. Water molecules attract each other strongly, and they link together to form a tight mesh. Would the same reactions occur in orange juice or other acid base substances. If the chalkiness comes from carbonates, the fizzing might be explained as a neutralization reaction that produces CO 2. To find out more, Coffey and a team of students tested the reactions between Diet Coke and fruit Mentos, mint Mentos, and various ingredients such as other mints, dish-washing detergent, table salt and sand. It takes energy to push water molecules away from each other to form a new bubble, or to expand a bubble that has already been formed. Inorganic chemistry Environmental chemistry Laboratory History of chemistry Miscellaneous Home. But caffeine-free Diet Coke did just as well, suggesting that caffeine does not accelerate the reaction, at least at the normal levels in the drink. I assume the pop is an acid mix and the mentos in some way reacts to it. By Hazel Muir Video: The explosive reaction produced by adding Mentos to Diet Coke has at last been explained. Experiments in a 2006 edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke.
Theories abound as to why this happens, with some bloggers speculating that it is an acid-base reaction because Coke is acidic. The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres. The world of Galileo: Eight days in Italy to discover the science of the Renaissance. But there have been no rigorous scientific studies of the reaction until now. So why do Mentos make diet soda foam so violently. Ordinarily, water resists the expansion of bubbles in the soda. The gelatin and gum arabic from the dissolving candy disrupts the water mesh, so it takes less work to expand bubbles. My 12 year old son saw the Mentos mint experiment with diet pop (add a Mentos mint and the pop reacts quite violently). Mentos have a strange chalky color and texture and they do taste rather like antacid tablets. They also compared reactions using other fizzy liquids such as caffeine-free and sugary colas, as well as soda water and tonic water.
