1. Does Mentos candy react with Coke? Why?

The explosive reaction between Mentos candy and Coke, particularly Diet Coke, is a fascinating example of physical chemistry in action. Here’s a simplified explanation.

When Mentos are dropped into a bottle of Coke, several factors contribute to the rapid release of carbon dioxide gas, creating the characteristic geyser:

1.1 Surface Area:

Mentos have a rough, bumpy surface that provides numerous nucleation sites. These are tiny, imperceptible craters where carbon dioxide bubbles can form.

1.2. Surfactant Effect:

Mentos act as a surfactant, which means they reduce the surface tension of the liquid. This allows the gas to escape more easily, forming bubbles.

1.3. Density and Sinking:

The Mentos candies are dense enough to sink quickly to the bottom of the bottle, which helps create a rapid release of gas from the bottom up, contributing to the fountain effect.

1.4. Ingredients:

The reaction is more vigorous with Diet Coke than regular Coke. This is because aspartame and benzonatate (preservatives used in artificially sweetened drinks) lower the surface tension more than sugar does, allowing for a more explosive reaction.

It’s important to note that the reaction is not a chemical one but a physical one. The carbon dioxide in the soda is already present and is simply released more rapidly when the Mentos are added. The combination of the Mentos’ surface properties and the composition of the soda creates the perfect conditions for a dramatic release of gas, resulting in the explosive fountain effect.
