The equation Na2S + O2 -> Na2SO3

1. Detailed information about the reaction Na₂S + O₂ -> Na₂SO₃

The above equation describes the oxidation process of sodium sulfide (Na₂S) in the presence of oxygen (O₂) to produce sodium sulfite (Na₂SO₃).

2. Reaction conditions

For the reaction to occur, appropriate temperature and pressure need to be provided. The reaction usually takes place at high temperatures and in the presence of oxygen.

3. Reaction Process

During the reaction process, sodium sulfide provides electrons to oxygen, causing oxygen to be reduced and sodium sulfide to be oxidized. The result of this process is the formation of sodium sulfite.

4. Phenomena occurring

When the reaction occurs, both reactants (Na₂S and O₂) gradually disappear and create a new product (Na₂SO₃). The color change of the reactant and the product can be observed, from the white color of sodium sulfide to the pale yellow of sodium sulfite.
