Categories: Chemical Reactions, Oxidation and Reduction

Alternative titles: Ice-Powered Fire, Sodium Peroxide and Water Reaction

Summary

Tissue paper (or another combustible material) is ignited using a chip of ice. The ice melts, releasing water, which reacts with sodium peroxide to produce sodium hydroxide, oxygen, and heat.

Procedure

  1. Tear or cut tissue paper into very fine pieces and pile them into a small cone shape about 5 cm high on an asbestos or tile plate.
  2. Place about half a teaspoon of sodium peroxide on top of the paper cone.
  3. Show students the small chip of ice and place it carefully on top of the sodium peroxide.
  4. Step back and observe as the ice melts, triggering the reaction that produces heat and reactive oxygen.
  5. Watch as the fine paper ignites into flames.

Safety Precautions

  • Perform only as a teacher demonstration—never student hands-on.
  • Sodium peroxide is highly reactive; handle with care using tongs and protective gear.
  • Always wear safety goggles, gloves, and a lab coat.
  • Conduct the experiment in a well-ventilated area or under a fume hood.
  • Keep a fire extinguisher or sand bucket nearby in case of uncontrolled flames.
  • Dispose of residues safely according to chemical waste regulations.

Questions to Consider

  • What reaction took place when the ice was added to sodium peroxide?
  • Why does burning require oxygen?
  • What was the role of sodium peroxide in this experiment?
  • What is the chemical equation for the reaction between sodium peroxide and water?
  • Is this reaction exothermic or endothermic?
  • What real-life processes also involve rapid oxidation with energy release (e.g., engines, metabolism)?
