what is produced when copper sulphate solution is mixed with ammonia solution?
Either copper(II) hydroxide or copper(II) ammine sulfate or both depending upon the strength and the amount of ammonia added. The first is Cu(OH)2, the second is Cu(NH3)4SO4
To determine what is produced when copper sulfate solution is mixed with ammonia solution, we need to understand the reaction between copper sulfate (CuSO4) and ammonia (NH3).
The reaction can be summarized as follows:
CuSO4 + 2NH3 → Cu(OH)2 + (NH4)2SO4
When copper sulfate is mixed with ammonia solution, copper(II) hydroxide (Cu(OH)2) is formed along with ammonium sulfate ((NH4)2SO4).
Copper(II) hydroxide (Cu(OH)2) is a blue precipitate that forms when copper sulfate reacts with ammonia. It is insoluble in water and can be visually identified by its blue color.
Ammonium sulfate ((NH4)2SO4) is a soluble salt that remains in the solution.
However, it is important to note that the specific products formed depend on the strength and amount of ammonia added. In some cases, copper(II) ammine sulfate (Cu(NH3)4SO4) may also be formed. Copper(II) ammine sulfate is a complex compound where copper is coordinated with four ammonia molecules.
Therefore, the possible products when copper sulfate solution is mixed with ammonia solution are copper(II) hydroxide (Cu(OH)2), ammonium sulfate ((NH4)2SO4), and copper(II) ammine sulfate (Cu(NH3)4SO4) if sufficient ammonia is present.
