The equation 6KMnO4 + 5H2SO4 -> 3K2SO4 + 6MnSO4 + 5H2O + 5O2

  1. Detailed Information about the Equation:
    The chemical equation described is the redox reaction between potassium permanganate (KMnO4) and sulfuric acid (H2SO4), resulting in the formation of potassium sulfate (K2SO4), manganese sulfate (MnSO4), water (H2O), and oxygen (O2).

  2. Reaction Conditions:
    This reaction takes place under high-temperature conditions and normal pressure.

  3. Reaction Process:
    When potassium permanganate and sulfuric acid are mixed together and the temperature is raised, they form potassium sulfate, manganese sulfate, water, and oxygen. In this reaction, KMnO4 is reduced from an oxidation state of +7 to +2 (in MnSO4), while O in H2SO4 is oxidized from an oxidation state of -2 to 0 (in O2).

  4. Phenomenon Occurring:
    During the reaction process, the color of the solution changes from the purple of KMnO4 to the pale pink of MnSO4. Simultaneously, bubbles of oxygen gas are released.
