The equation is 3KMnO4 + 2H2S -> 3K2SO4 + 2MnSO4 + 2H2O + 3S.

  1. Detailed information about the equation:
    The equation describes the reaction between potassium permanganate (KMnO4) and hydrogen sulfide (H2S). The products of this reaction are potassium sulfate (K2SO4), manganese sulfate (MnSO4), water (H2O), and solid sulfur (S).

  2. Reaction conditions:
    This reaction occurs under standard temperature and pressure conditions. However, the reaction speed can be increased if the temperature is raised.

  3. Reaction process:
    Hydrogen sulfide (H2S) reacts with potassium permanganate (KMnO4) to form potassium sulfate (K2SO4), manganese sulfate (MnSO4), water (H2O), and solid sulfur (S). Here, KMnO4 acts as a strong oxidizing agent, oxidizing H2S to S and is reduced to MnSO4.

  4. Phenomena occurred:
    When the reaction takes place, the purple liquid of potassium permanganate (KMnO4) gradually turns into the pale pink of manganese sulfate (MnSO4), and yellow solid sulfur is produced.
