Introduction

In this experiment, a exothermic reaction is going to take place. It is an exothermic reaction because heat is being released during the chemical reaction that takes place. The chemical reaction happens because of the hydrogen peroxide and the sodium iodine reacting with each other. There is also soap in the reaction, which makes the bubbles that cause the foam. These bubbles are filled with oxygen from the chemical reaction. Also, hydrogen peroxide is a oxidizing substance which can be harmful.

Question

What will happen when sodium iodide solution is added to hydrogen peroxide and soap?

Questions

1. Will the reaction rate change with different concentrations of H2O2?

-Yes, because the catalyst will have more to break down, causing the reaction to take longer.

2. How much O2 gas is being produced?

-As much as there is in the bubbles that the reaction make.

3. What is the function of KI in the reaction?

-It is the catalyst.

4. Can other catalysts be used in this reaction?

-Yes.

5. When you buy H2O2 in drug stores it is in a brown bottle. Why is this?

-Because it has a lower concentration.

6. How is this reaction similar to metabolic processes in humans?

-It shows the breakdown of a substance.

7. How is the H2O2 used as an oxidizing agent in the human body?

-It can be used to treat diseases and as an antiseptic.
