Exploring the Elephant Toothpaste Reaction

Front

What is the main chemical reaction that occurs in the elephant toothpaste experiment?

Back

Decomposition of hydrogen peroxide.

Front

Which substance is commonly used as a catalyst in the elephant toothpaste experiment?

Back

Yeast.

Front

How could you modify the experiment to produce a slower or faster reaction?

Back

Modify temperature and concentration of reactants.

Front

Explain the scientific principle behind the formation of foam in the elephant toothpaste experiment.

Back

The formation of foam is due to the rapid release of oxygen gas from the decomposition of hydrogen peroxide, which is trapped by soap, creating bubbles.

Front

What is the chemical formula for hydrogen peroxide, the main reactant in the elephant toothpaste experiment?

Back

H_2O_2.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What role does soap play in the elephant toothpaste experiment?

Back

Soap helps trap the oxygen gas released during the decomposition of hydrogen peroxide, forming bubbles and creating foam.

Front

What is the state of hydrogen peroxide at room temperature?

Back

Liquid.

Front

What safety precautions should be taken during the elephant toothpaste experiment?

Back

Wear safety goggles and gloves, and conduct the experiment in a well-ventilated area.

Front

What is the purpose of using yeast in the elephant toothpaste experiment?

Back

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