Sodium Peroxide ignition

Yellow powder makes rice krispies flammable.

Scientific name: Sodium peroxide decomposes with release of a big amount of oxygen which oxidizes the organic matter.

Wear eye protection goggles and gloves. There is a serious fire risk - a fire extinguisher should be ready. Make sure there is nothing flammable nearby.

Always follow general safety recommendations. Please note that conducting chemistry experiments you must comply with the relevant legal procedures in your country.

Reaction formula

Na2O2 + 2H2O → 2NaOH + H2O2

2H2O2 → 2H2O + O2

C6H12O6 + 6O2 → 6CO2 + 6H2O

Step-by-step instruction

WARNING! This experiment is dangerous! You should NOT perform this at home. ONLY carry out this experiment, if you are a trained chemist, and you understand local safety and legal requirements, which are required to perform such experiments

  1. Put some organic matter for example rice krispies into a fire-proof beaker.
  2. Sprinkle the rice krispies with sodium peroxide powder.
  3. Add a few drops of water. The rice krispies burn rapidly!

Scientific background

Sodium peroxide contains two oxygen atoms still joined together like in an oxygen molecule. These two atoms make the molecule rather reactive. It readily decomposes in water. During sodium peroxide decomposition a lot of molecular oxygen is released. If there is some organic matter in the reaction area it is oxidized with oxygen and burns.
