The equation 2HNO3 + 2Na2SO3 -> 2Na2SO4 + 2NO + H2O

  1. Detailed information about the equation 2HNO3 + 2Na2SO3 -> 2Na2SO4 + 2NO + H2O:

    • This equation describes the reaction process between nitric acid (HNO3) and sodium sulfite (Na2SO3) to produce sodium sulfate (Na2SO4), nitrogen monoxide (NO) and water (H2O).
    • The number of moles of each reactant and product has been balanced in the equation.
    • This reaction is a redox reaction.

  2. Reaction conditions:

    • The reaction occurs at normal temperature.
    • There needs to be direct contact between the two reactants, HNO3 and Na2SO3.

  3. The reaction process:

    • Nitric acid (HNO3) will react with sodium sulfite (Na2SO3) to produce sodium sulfate (Na2SO4), nitrogen monoxide (NO) and water (H2O).
    • HNO3 acts as an oxidizing agent, while Na2SO3 acts as a reducing agent.

  4. Phenomena that occur:

    • When nitric acid (HNO3) reacts with sodium sulfite (Na2SO3), green NO gas will appear.
    • In addition, the alkaline product of the reaction, sodium sulfate (Na2SO4), which is a white solid, will be produced.
