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 salt gives flames green color?
There are two products that will give flame a green color. Boric acid and copper sulfate. Copper sulfate is the salt, however.
Which colour of copper sulphate solution change when iron dipped in it?
It may seem like the iron rusts, but it doesn't. The chemical formula for copper sulfate is CuSO4, or, 1 copper atom, 1 sulfur atom, and 4 oxygen atoms to each molecule. When the iron is placed in the solution of copper sulfate, it replaces the copper in the solution, turning copper sulfate into iron sulfate (FeSO4) and pure copper collects on the iron. This can be proved by removing the copper and seeing that the iron has lost a lot of its mass, as in, it lost mass to the copper sulfate. The iron (steel wool) takes on a pinkish color which is metallic copper deposited when the solution forms iron sulfate.
What color do you observe for the solution of hydrated copper(II) chloride in water?
The solution color of cupric oxide is blue to green.
What is the color of copper sulphate?
Copper sulfate itself is white/colorless when anhydrous. However, it's hygroscopic and the pentahydrate (the usual form) is blue... in fact, it's just about the same color as the sidebar over to the left there.
What is Chalcanthite made of?
The mineral chalcanthite is composed of hydrous copper sulfate. It is translucent and a rich blue in color. Chalcanthite has a hardness of 2.5. The oxidation of copper sulfides is what causes it to form in nature.
What does a primary amine do to the color of copper sulfate solution?
It will darken the copper (II) sulfate solution.
What happens when you added Ammonia to copper sulfate?
It forms a complex - Copper (tetraamine) sulfate which is a deep inky blue color
What happen when copper sulfate mixed with ammonia?
It turns blue in color. Because of Ammonia reacts with Cu+2.
What color of cupric sulfate mix into the water?
Blue is the solution's color When blue CuSO4.5H2O (copper(II) sulfate pentahydrate) is dissolved, the solution turns blue. When white CuSO4 (anhydrous copper(II) sulfate) is dissolved, the solution turns also blue.
Why does the color of copper sulfate solution changes during electrolysis?
The color fades as there is a discharge of copper two ions to form copper atoms
How do you turn a stainless silver spoon into a copper spoon?
copper sulfate, or Cu(SO4)(aq). The first clue we have that it is, in fact, copper sulfate is its reaction with the ammonia solution. When the deep blue color formed(in the reaction), the solution formed is [Cu(NH3)4](OH)2(aq), which gives off a bluish color. Secondly, upon acidification of [Cu(NH3)4](OH)2(aq), we see the solution become practically colorless again, The third clue when potassium ferrocyanide is mixed with copper sulfate, it also forms a red precipitate. And last but not least, when copper sulfate reacts with steel, which is primarily iron, copper is formed. This is why the steel changed to a bronze like metal.mystery=copper sulfate
What happens when copper sulfate and steel wool is mix?
IF THE COPPER SULFATE DISSOLVES IN WATER, HAS A BLUE COLOR. WHEN STEEL WOOL IS MIXED WITH COPPER SULFATE,, THE STEEL WOOL DISSAPEARS, A BROWNISH SOLID FORMS, AND THE COLOR OF THE SOLUTION CHANGES FROM BLUE TO GREEN.Copper is produced.
What is would you expect to see when zinc is added to Copper Sulphate?
there would be a single replacement reaction where the copper forms on the top of the zinc and the blue color of the copper sulfate would get lighter and eventually you would end up with zinc sulfate and copper
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.
The blue color in the copper sulfate solution is due to the presence of what ion?
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
What salt gives flames green color?
There are two products that will give flame a green color. Boric acid and copper sulfate. Copper sulfate is the salt, however.
What happens when copper sulfate and magnesium react?
There is a slight color change...We did this in a lab in class. It tarnished slightly. This may be incorrect. I'm not sure...
