This is a chemical reaction between copper (II) sulfate (CuSO4) and sodium sulfide (Na2S) to form copper sulfide (CuS) and sodium sulfate (Na2SO4). The reaction has the characteristic of a two-directional substitution reaction.
The chemical reaction is as follows:
CuSO4 (aq) + Na2S(aq) -> CuS(s) + Na2SO4(aq)
- Reaction conditions:
The reaction occurs when the two reactants are mixed together under standard temperature and pressure conditions.
- Reaction process:
When copper (II) sulfate (CuSO4) and sodium sulfide (Na2S) are mixed together, they will react and form copper sulfide (CuS) and sodium sulfate (Na2SO4).
- Phenomena that occur:
CuSO4 is blue. When reacting with Na2S, the solution will turn black due to the presence of CuS.
