About

What will the chemical reaction be when hydrogen peroxide is mixed with sodium iodine solution?

Materials

The materials needed are:

• • graduated cylinders

  • food coloring

  • tray

  • soap

  • hydrogen peroxide

  • sodium iodine solution

  • gloves

Procedure

1. Put one graduated cylinder in the tray.

2. Put 20mL of 30% hydrogen peroxide in the beaker. Make sure gloves are worn.

3. Measure out 10mL of soap and add it to the hydrogen peroxide.

4. Add food coloring

5. Measure 5mL of sodium iodine and quickly add it to the beaker in the tray.

6. Step back and observe the reaction.

Scientific Principle

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.

Exothermic chemical reaction

- Heat is released.

-Gives energy to surroundings.

Safety

Make sure not to touch the foam as it is very hot.
