The equation is CuSO4 + H2S -> CuS + H2SO4

Detailed information about the chemical equation CuSO₄ + H₂S -> CuS + H₂SO₄:

This equation describes the reaction between copper (II) sulfate (CuSO₄) and hydrogen sulfide (H₂S) to produce copper (II) sulfide (CuS) and sulfuric acid (H₂SO₄).

Reaction conditions:

The standard conditions are 1 atm pressure, 25°C temperature. However, this reaction does not require strict temperature and pressure requirements, just enough to encourage the reaction to occur.

Reaction process:

The transformation of CuSO₄ into CuS and H₂SO₄ occurs through the action of H₂S, a reducing agent with the ability to convert Cu₂+ ions in CuSO₄ into CuS.

Phenomena occurring:

The phenomena of this reaction can be identified by changes in color. Copper (II) sulfate (CuSO₄) is blue in solution, after reacting with H₂S, it produces black copper sulfide (CuS) and sulfuric acid. During the reaction, the solution changes from blue to black.
