The reaction equation shows that 4 moles of nitric acid (HNO3) react with 6 moles of hydrogen sulfide (H2S) to form 4 moles of sulfuric acid (H2SO4), 8 moles of nitric oxide (NO) and 3 moles of water (H2O).
- Reaction conditions:
The specific conditions for the reaction may vary depending on factors such as concentration, pressure, and temperature. However, this reaction typically occurs under normal temperature and pressure conditions.
- Reaction process:
The reaction begins when nitric acid acts on hydrogen sulfide. The result of the chemical reaction is the formation of products such as sulfuric acid, nitric oxide, and water.
- Observed phenomena:
When the reaction occurs, an observable phenomenon is the color change and gas release. The product nitric oxide (NO) is a brown gas, so a color change can be observed. There may also be heat release because the reaction is exothermic.
