The chemical equation is 3KMnO4 + 5H2O2 -> 3KOH + 3MnO2 + 5H2O + 2O2

  1. The chemical equation shown above represents the reaction process between potassium permanganate (KMnO4) and hydrogen peroxide (H2O2) to produce potassium hydroxide (KOH), manganese dioxide (MnO2), water (H2O) and oxygen (O2).

  2. Reaction conditions: The reaction can take place at room temperature and does not require the presence of a catalyst.

  3. Reaction process: During the reaction process, potassium permanganate and hydrogen peroxide interact with each other. KMnO4 is reduced from an oxidation state of +7 to +4, forming MnO2. H2O2 is also reduced, the oxidation state of oxygen increases from -1 to 0, forming O2. KMnO4 and H2O also react with each other to produce KOH and H2O.

  4. Occurring phenomena: When the reaction occurs, the purple color of potassium permanganate disappears and turns into the brown-black color of manganese dioxide. At the same time, free oxygen gas is generated.
