The chemical equation Na2S + H2O -> 2NaOH + H2S

Detailed information about the reaction Na₂S + H₂O -> 2NaOH + H₂S:
The equation above describes the reaction process between sodium sulfide (Na₂S) and water (H₂O), resulting in sodium hydroxide (NaOH) and hydrogen sulfide (H₂S).

Reaction conditions:
The reaction occurs at room temperature and standard pressure.

Reaction Process:
When sodium sulfide (Na₂S) reacts with water (H₂O), the sulfur (S) atom in Na₂S combines with the hydrogen (H) atom in H₂O to form hydrogen sulfide (H₂S), while the two sodium (Na) atoms in Na₂S combine with the oxygen (O) atom in H₂O to form sodium hydroxide (NaOH).

Phenomenon that occurs:
During the reaction, we can observe the phenomenon of the release of a foul-smelling gas (H₂S). Simultaneously, the solution will change from white (the color of water) to clear (the color of NaOH solution).
