- Detailed information about the H2O2 -> H2O + O2equation -> :
- The left side of the equation is hydrogen peroxide (H2O2), a very active substance in chemical reactions. It has the ability to decompose into water (H2O) and oxygen gas (O2), substances represented on the right side of the equation.
- This equation also shows that conservation of mass is an important principle in chemistry. The total number of hydrogen and oxygen atoms before and after the reaction remains unchanged.
- Reaction conditions:
- This reaction occurs naturally at room temperature. However, the reaction rate is quite slow and can be increased by adding catalysts such as manganese dioxide (MnO2).
- Light can also accelerate the reaction rate.
- Reaction Process:
- When H2O2 comes into contact with a catalyst or light, it begins to decompose into water and oxygen gas.
- During the decomposition process, the H2O2 molecules are broken down and rearranged into H2O and O2 molecules.
- Phenomena observed:
- When the reaction occurs, you will see bubbles of oxygen gas being released.
- If the reaction is performed in a water solution, you will also see the solution becoming clearer due to the release of oxygen gas.
