Is Diet Coke and Mentos a chemical or physical change?

Is Diet Coke and Mentos a chemical or physical change?

physical reaction
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.

What is the reaction between Coke and Mentos called?

nucleation
After a lot of debate, scientists are now saying that the primary cause of Coke & Mentos geysers is a physical reaction, not a chemical reaction. 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.

What is the chemical equation for Mentos?

Originally Answered: What is the chemical equation of Diet Coke and Mentos? There is no chemical reactions, therefore no equation. The mentoes provide nucleation sites for the dissolved carbon dioxide to come out of solution.

Is the eruption of cola and Mentos a result of an acid base reaction?

It’s Not an Acid/Base Reaction But they do have one thing in common: carbon dioxide. On the other hand, when you drop a Mentos candy into a bottle of cola, the carbon dioxide gas was already present in the soda to begin with, yet it seems to suddenly erupt.

What is a physical reaction?

A physical reaction occurs when molecules undergo a molecular rearrangement to produce a physical change. The molecules are not chemically altered. So, the difference is that with a physical reaction, a chemical change in the molecule is not observed, but a physical change is observed.

Why does Diet Coke react more with Mentos?

Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual.

What is the chemical composition of Diet Coke?

CARBONATED WATER, CARAMEL COLOUR, PHOSPHORIC ACID, NATURAL FLAVOUR, ASPARTAME (CONTAINS PHENYLALNINE), POTASSIUM BENZOATE, POTASSIUM CITRATE, ACESULFAME-POTASSIUM, CAFFEINE.

Why does Diet Coke react the most with Mentos?

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.

What is the science behind Mentos and soda?

A Mentos dropped into a bottle of soda acts as a surfactant, meaning it reduces the surface tension of the soda. Water molecules are polar and attracted to each other. Anything that breaks them apart allows for bubbles of carbon dioxide gas to form in the solution.

What is chemical and physical?

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.

What will happen if you put Mentos in Diet Coke?

A Mentos mint causes a bottle of Diet Coke to fizz over because the irregular surface of the mint provides numerous nucleation sites for the carbonation in the Diet Coke. This rapid nucleation is what makes the Coke fizz over. Show Comments.

Do you have to use Diet Coke With Mentos?

To enforce the fairness factor, you must stick with one brand of soda for the entire test. Let’s use Diet Coke in this example. You’ll want to purchase three bottles of Diet Coke and two rolls of Mentos. You’re going to set up three tests—warm soda, room temperature soda, and cold soda.

Can drinking Coca Cola with Mentos harm you?

Swigging some Coke and swallowing some Mentos will essentially cause a lot of the carbon dioxide trapped in the soda in your stomach to suddenly bubble and try to escape. However, your stomach is not enough of a seal to keep this sudden pressure change contained inside. If this were the case, eating Mentos and drinking soda may indeed be dangerous .

Why do Mentos explode in Diet Coke?

In the Diet Coke bottle the Mentos candy provides a rough surface that allows the bonds between the carbon dioxide gas and water to break more easily, helping to create carbon dioxide bubbles. Because Mentos candies are rather dense, they sink rapidly through the liquid, causing a fast, large eruption.
