The equation ZnS + H2SO4 -> ZnSO4 + H2S

1. Detailed information about the equation ZnS + H₂SO₄ -> ZnSO₄ + H₂S

This equation describes the chemical reaction process between zinc sulfide (ZnS) and sulfuric acid (H₂SO₄), producing zinc sulfate (ZnSO₄) and hydrogen sulfide (H₂S).

2. Reaction conditions

This reaction is usually conducted under high-temperature conditions (around 200-300 degrees Celsius) and relatively high pressure.

3. 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.

4. 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.
