What is the reaction o copper and ammonia?
When copper metal reacts with ammonia, it forms a deep blue complex called tetraamminecopper(II) complex. This reaction involves the displacement of water molecules in the copper sulfate solution by ammonia molecules to form the complex. The blue color is due to the absorption of specific wavelengths of light by the complex.
How does ammonia react with solution with copper ion?
Ammonia can react with a solution containing copper ions to form a deep blue complex known as tetraamminecopper(II) complex. This reaction occurs through coordination bonding between ammonia molecules and copper ions, resulting in the formation of the complex. The intensity of the blue color can vary depending on the concentration of ammonia and copper ions in the solution.
Why a pale blue precipitate of copper hydroxide is formed when ammonia is passed through copper sulphate?
When ammonia is added to a solution of copper sulfate, it forms a complex with the copper ions to produce a pale blue precipitate of copper hydroxide. The complex forms because ammonia acts as a ligand, coordinating with the copper ions to create a stable compound. This reaction is a result of the displacement of the sulfate ions by ammonia in the copper sulfate solution.
What is ammonia used to test for copper in a solution?
Ammonia is used to test for the presence of copper in a solution because it forms a deep blue complex with copper ions. This complex is known as Schweizer's reagent and can be used as a qualitative test for the presence of copper ions.
What happen when copper sulfate mixed with ammonia?
When copper sulfate is mixed with ammonia, a deep blue precipitate of copper hydroxide forms. This reaction occurs due to the ammonia forming a complex with the copper ions in the copper sulfate solution.

What is Color of copper sulfate solution and ammonia?
Copper sulfate (II) CuSO4 is blue; ammonia is a colorless gas. If you mix ammonia water and copper sulfate solution, you will actually form a Brilliant blue copper-ammonium complex that is very pretty. Copper sulfate is blue by itself and anhydrous ammonia is a clear gas with a choking odor.

Ammonia is used to test for the presence of copper in a solution because it forms a deep blue complex with copper ions. This complex is known as Schweizer's reagent and can be used as a qualitative test for the presence of copper ions.
Why does excess ammonia have to be added to copper ions solution to obtain the deep blue complex of copper tetra amine?
When excess ammonia is added to a solution of copper(II) ions, a complex will form between the ammonia molecules and copper(II) ions, dissolving the copper hydroxide precipitate that initially forms to form a deep-blue solution, Cu(NH3)42+. The ammonia molecules attach one at a time, and in between each attachment, there is a chemical equilibrium. The more ammonia is added, the more complex is formed, as the equilibrium is pushed to the product side. The blue color is the result of the complex absorbing light in the visible light spectrum, and having a concentration high enough for the eyes to detect.
What happen when copper sulfate mixed with ammonia?
When copper sulfate is mixed with ammonia, a deep blue precipitate of copper hydroxide forms. This reaction occurs due to the ammonia forming a complex with the copper ions in the copper sulfate solution.
What is the reaction between ammonia and copper sulfate?
The reaction between ammonia and copper sulfate forms a deep blue complex called tetraamminecopper(II) sulfate, which has the chemical formula [Cu(NH3)4]SO4. This complex is formed as the ammonia molecules displace the water molecules coordinated to the copper ions in copper sulfate.
Is tetraamine copper sulphate a complex salt?
Yes, tetraamine copper sulfate is a complex salt. It is a coordination complex formed by the interaction of copper sulfate with four ammonia molecules to form a stable complex ion.
What happens when copper and ammonia comes into contact?
When copper and ammonia come into contact, they can form a deep blue complex called [Cu(NH3)4]2+. This process is a type of coordination reaction in which the ammonia molecules coordinate with the copper ions to form the complex. The color change is due to the absorption of light at specific wavelengths associated with the complex.
Why does the precipitation of copper ion dissolve in excess aqueous ammonia?
Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
What happens when ammonia is added to copper sulfate?
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
