This equation describes the chemical reaction process between zinc sulfide (ZnS) and sulfuric acid (H2SO4), producing zinc sulfate (ZnSO4) and hydrogen sulfide (H2S).
- Reaction conditions
This reaction is usually conducted under high-temperature conditions (around 200-300 degrees Celsius) and relatively high pressure.
- Reaction process
During the reaction process, the zinc ion in ZnS will react with the sulfate ion in H2SO4 to form ZnSO4, while the sulfide ion (S) in ZnS will react with the hydrogen ion in H2SO4 to create H2S.
- Phenomena occurring
When the reaction occurs, we will see a yellowish-green gas (H2S) being produced. For users, H2S smells rotten, similar to the smell of rotten eggs. It can also cause poisoning if inhaled at high concentrations. Meanwhile, a white solid substance (ZnSO4) is also produced during this process.
