Exploring the Elephant Toothpaste Reaction

Front

What is the elephant toothpaste reaction?

Back

A chemical reaction that produces a large amount of foam, resembling toothpaste, through the decomposition of hydrogen peroxide.

Front

Which gas is produced in the elephant toothpaste reaction?

Back

Oxygen gas.

Front

What is a catalyst?

Back

A substance that speeds up a chemical reaction without being consumed in the process.

Front

What role does yeast play in the elephant toothpaste experiment?

Back

Yeast acts as a catalyst to speed up the decomposition of hydrogen peroxide.

Front

What is the main reactant in the elephant toothpaste reaction?

Back

Hydrogen peroxide (H2O2).

Front

How does food coloring affect the elephant toothpaste experiment?

Back

Food coloring enhances visibility of diffusion and interactions in the experiment.

Front

What is one way to measure the rate of reaction in the elephant toothpaste experiment?

Back

By the height of the foam produced over time.

Front

What is the chemical formula for water?

Back

H2O.

Front

What is the purpose of using dish soap in the elephant toothpaste reaction?

Back

Dish soap helps trap the oxygen gas produced, creating foam.

Front

What happens to the temperature of the reaction mixture during the elephant toothpaste experiment?

Back

The temperature increases due to the exothermic nature of the reaction.
