The above equation represents the chemical reaction process between sodium sulfide (Na2S) and nitric acid (HNO3), resulting in the formation of sodium nitrate (NaNO3), gaseous SO2, and water (H2O).
- Conditions for the reaction:
The reaction takes place in an acidic environment, at room temperature.
- Reaction Process:
During the reaction process, the sodium cation from sodium sulfide (Na2S) will combine with the nitrate anion from nitric acid (HNO3), forming sodium nitrate (NaNO3). The sulfide anion from Na2S will combine with the proton from HNO3 to form gaseous SO2 and water (H2O).
- Phenomena occurring:
When Na2S reacts with HNO3, it generates gaseous SO2. The resulting sodium nitrate is a white solid that dissolves in water.
