This equation describes the reaction between sodium peroxide (Na2O2) and heat to produce sodium oxide (Na2O) and oxygen (O2). It is a redox reaction, in which the sodium in sodium peroxide remains unchanged, while the oxygen in sodium peroxide is reduced from an oxidation state of +1 to 0 in oxygen gas.
- Reaction conditions
For the reaction to occur, it requires high temperature. When the temperature increases, the reaction rate will also increase.
- Reaction process
As the temperature increases, sodium peroxide starts to decompose into sodium oxide and oxygen. The oxygen is then released into the air as a gas.
- Phenomena occurring
When the reaction occurs, we can clearly see the oxygen gas being released. In addition, sodium peroxide is converted into sodium oxide, which is a white solid.
