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

  1. Detailed information about the reaction 2KMnO4 + 3H2S -> K2SO4 + 2MnSO4 + 3H2O + 3S

    • The equation above describes the chemical process occurring between potassium permanganate (KMnO4) and hydrogen sulfide (H2S) to create potassium sulfate (K2SO4), manganese sulfate (MnSO4), water (H2O), and sulfur (S).
    • The equation has the balanced coefficients of 2:3:1:2:3:3.

  2. Reaction conditions

    • This reaction occurs in an acidic environment.
    • The reaction temperature does not need to be too high.

  3. The Reaction Process

    • Potassium permanganate is reduced from the manganese (VII) state to the manganese (II) state, while hydrogen sulfide is oxidized from the sulfide (-II) state to sulfur (0).
    • The number of electrons transferred from KMnO4 to H2S is equal, ensuring the conservation of charge rule in the chemical reaction.

  4. Phenomena occurring

    • When the two substances react, the purple solution of potassium permanganate will turn into the pale pink of manganese sulfate.
    • The sulfur product will form as a yellow precipitate.
