* Decomposition of Hydrogen Peroxide: Hydrogen peroxide is unstable and readily decomposes into water (H₂O) and oxygen gas (O₂). The sugar acts as a catalyst, speeding up this decomposition process.
* Oxidation of Sugar: The oxygen released from the decomposition of hydrogen peroxide reacts with the sugar molecules. This is an oxidation reaction where the sugar molecules lose electrons. The exact products of this oxidation are complex and depend on factors like concentration and temperature.
The overall reaction can be summarized as:
Hydrogen Peroxide (H₂O₂) → Water (H₂O) + Oxygen (O₂)
Sugar (C₁₂H₂₂O₁₁) + Oxygen (O₂) → Oxidation Products
Important Note: This reaction is exothermic, meaning it releases heat. The combination of sugar and hydrogen peroxide can be dangerous as it can lead to a rapid release of heat and potentially cause a fire or explosion if the mixture is not carefully controlled.
In summary:
* Chemical Change: The chemical composition of the reactants (hydrogen peroxide and sugar) changes, resulting in new products (water, oxygen, and oxidized sugar).
* Catalyst: Sugar acts as a catalyst, speeding up the decomposition of hydrogen peroxide.
* Exothermic: The reaction releases heat.
* Potential Danger: The reaction can be dangerous and should be handled with caution.
