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.
What is soluble copper?
Well soluble means able to dissolve so soluble copper is copper that dissolves in a solvent (liquid)
Are ammonia and copper mixed together a chemical?
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
How can we clean copper oxide?
Copper oxides are soluble in acids.
Is copper iodide soluble in water?
No. Copper iodide is insoluble in water.
What is the colour of copper ammonia complex?
Copper ammine (not a misspelling) complexes are a very deep blue.

What happens when you added Ammonia to copper sulfate?
It forms a complex - Copper (tetraamine) sulfate which is a deep inky blue color
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 is the reaction of copper and ammonium hydroxide and hydrogen peroxide?
In the presence of ammonia and copper, hydrogen peroxide will decompose, liberating oxygen gas. The oxygen gas dissolves in the solution and oxidizes copper to copper (2+). Then the ammonia reacts with the Cu2+ forming a complex with deep blue color.
Why you use alcohol in preparation of tetraamine copper sulphate monohydrate?
we use alcohol in its preparation to decrease solubility of ammonia in water so that it will react with copper to form complex and decrease solubility of complex will crystallize it out.
What is soluble copper?
Well soluble means able to dissolve so soluble copper is copper that dissolves in a solvent (liquid)
How can you determine the stoichiometry of cuprammonium ion using partition coefficient between water and chloroform?
take a aqueous solution cupric salt like copper sulfate , add excess of ammonia to it , as the complex will be formed the color will be deep blue , now add chloroform to it as only ammonia will be soluble in it , ammonia will go in the chloroform layer , now separate the layers using a seperatory funnel and titrate both the layers by using a base and indicator , by taking the difference u will no the amount of copmplexed ammonia and can determine the formula of the copmlex , the answer will be near to 4 molecules of ammonia per ion of copper .
What is the reaction o copper and ammonia?
Copper is a metal element. It is not reacting with ammonia.
Why you use alcohol in preparation of tetraamine copper 2 sulphate monohydrate?
we use ethanol to decrease the solubility of ammonia in water,so that ammonia easily combines with copper in less polar environment now..in this way solubility is decreased and the complex i.e tetraammine copper 2 sulphate crystallizes out..
Which complex of Cu is formed when Ammonia reacts with copper two hydroxide?
The complex formed is diaquatetraaminecopper (II) ions. It has the formula [Cu(H2O)2(NH3)4]2+
What happens when EDTA is added to a solution of ammonia and copper sulphate?
The water soluble copper sulfate produces Cu(II) ions in solution. The soluble ammonium hydroxide produces ammonium ions and hydroxide ions in solution in equilibrium with ammonia and water. NH4OH(aq) ↔ NH3(aq) + H2O(l) The ammonia molecules react with the cooper ion to produce a complex ion of Cu(II) coordinated with four ammonia molecules. Cu2+(aq) + 4 NH3(aq) → [Cu(NH3)4]2+(aq) That complex ion in turn associates with a water molecule and the sulfate ion resulting in the products of the overall reaction. CuSO4(aq) + 4 NH4OH(aq) → Cu(NH3)4SO4H2O(s) + 3 H2O(l)
