  1. When heated with oxygen and carbon dioxide, sodium sulfide can oxidize to sodium carbonate and sulfur dioxide: 2 Na 2 S + 3 O 2 + 2 CO 2 2 Na 2 CO 3 + 2 SO 2. Oxidation with hydrogen peroxide gives sodium sulfate: [8] Na 2 S + 4 H 2 O 2 → 4 H 2 O + Na 2 SO 4. Upon treatment with sulfur, sodium polysulfides are formed: 2 Na 2 S + S 8 → 2 ...

  2. A chemical equation represents a chemical reaction. It shows the reactants (substances that start a reaction) and products (substances formed by the reaction). For example, in the reaction of hydrogen (H₂) with oxygen (O₂) to form water (H₂O), the chemical equation is: H 2 + O 2 = H 2 O.

  3. Chemical Properties of Sodium sulfide – Na 2 S. Sodium sulfide dissolves in water to form its corresponding ions. The reaction is as below. Na2S + H2O 2Na+ + HS– + OH–. It can be easily oxidised when heated it forms sodium carbonate and sulfur dioxide. 2Na2S + 3O2 + 2CO2 → 2Na2CO3 + 2SO2.

  4. 2NaOH(aq)+H2S(g)→2H2O(l)+Na2S(aq) This is an acid-base reaction (neutralization): NaOH is a base, H2S is an acid. Appearance: White, waxy, opaque crystals ; White hygroscopic solid in various forms ; Colorless to white, odorless solid (flakes, beads, granular form).

  5. 24 Οκτ 2023 · Sodium sulfide is the chemical compound with the chemical formula Na2S, or more commonly its nonahydrate form Na2S·9H2O. 1. Properties. Chemical. Sodium sulfide reacts with acids to release hydrogen sulfide. Na 2 S + 2 HX → H 2 S + 2 NaX. Physical. Sodium sulfide is a white solid, though impure samples can be yellow or reddish.

  6. Sodium sulfide. Molecular formula: Na 2 S. Average mass: 78.040. Monoisotopic mass: 77.951610. ChemSpider ID: 14120.

  7. Sodium Sulfide – Na 2 S – Chemical Properties. Sodium sulfide dissolves in water and forms the ions it needs. The following is the reaction. Na 2 S + H 2 O 2 Na+ + HS – + OH – When heated, it quickly oxidized to generate sodium carbonate and sulphur dioxide. 2Na 2 S + 3O 2 + 2CO 2 → 2Na 2 CO 3 + 2SO 2
