The equation Na2O + SO2 -> 2Na2SO3

  1. Detailed information about the equation Na2O + SO2 -> 2Na2SO3:

    • This equation describes the process of the combination of sodium oxide (Na2O) with sulfur dioxide (SO2) to form sodium sulfite (Na2SO3).
    • According to the balanced equation, one mole of Na2O reacts with one mole of SO2 to produce two moles of Na2SO3.

  2. Reaction conditions:

    • This reaction requires high temperature and pressure to occur.
    • The reaction environment should be air, where O2 is present.

  3. Reaction process:

    • In the initial step, sodium oxide (Na2O) reacts with sulfur dioxide (SO2) to form sodium sulfite (Na2SO3).
    • The reaction process continues until one of the reactants is exhausted.

  4. Occurrence phenomena:

    • During the reaction process, sulfur dioxide is absorbed into the sodium sulfite solution.
    • The solution after the reaction will be white due to the appearance of sodium sulfite.
