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 happens when strip of zinc is dipped in copper sulphate solution?
When a strip of zinc is dipped in copper sulfate solution, a single displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the copper sulfate solution, forming zinc sulfate and depositing elemental copper on the strip. The solution changes color from blue (due to the copper sulfate) to colorless as zinc sulfate forms, and copper can be seen as a reddish-brown precipitate on the zinc strip.
What is the original colour of fehlings a solution?
Fehling's A solution is blue in color due to the presence of copper sulfate.
What happens when zinc granules are dipped in copper sulphate solution?
When zinc granules are dipped in copper sulfate solution, a displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the solution, resulting in the formation of zinc sulfate and elemental copper. The solution changes color from blue (copper sulfate) to colorless (zinc sulfate), and reddish-brown copper deposits can be seen on the zinc granules. This reaction highlights the reactivity series of metals, where zinc is higher than copper.
What dissolves into water and it is blue solution?
Copper sulfate (CuSO₄) is a common compound that dissolves in water to produce a blue solution. When added to water, it dissociates into copper ions and sulfate ions, giving the solution its characteristic blue color. This solution is often used in various applications, including agriculture and chemistry demonstrations.
What color before the reaction takes place when zinc is placed copper ll sulphate?
Before the reaction takes place, the copper(II) sulfate solution is typically blue in color due to the presence of copper ions. When zinc is added, the blue color gradually fades as the reaction occurs, leading to the formation of colorless zinc sulfate and precipitating copper metal.
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 happens when copper sulfate was added to water?
When copper sulfate is added to water, it dissociates into copper ions and sulfate ions. The copper ions give the solution a blue color, while the sulfate ions do not impact the color. The solution becomes a blue color due to the presence of copper ions.
What is the colour of the copper sulfate solution when zinc granules are added to it?
The color of the copper sulfate solution changes from blue to colorless when zinc granules are added to it. This is because zinc displaces copper in the solution through a chemical reaction, forming zinc sulfate and leaving the solution without copper ions responsible for its blue color.
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.
Why does the color of copper sulphate change when an iron nail is dipped in it?
When an iron nail is dipped in copper sulfate solution, a displacement reaction occurs. Iron is more reactive than copper, so it displaces copper in the solution and forms iron sulfate. This reaction causes the color change from blue (copper sulfate) to green (iron sulfate) as the copper ions are replaced by iron ions in the solution.
What will happen if you put an iron nail in a copper sulfate solution?
When an iron nail is placed in a copper sulfate solution, a single displacement reaction occurs. The iron will displace the copper in the solution, forming iron sulfate and depositing copper on the nail, causing it to turn a brownish color due to the presence of copper.
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.
What does a primary amine do to the color of copper sulfate solution?
A primary amine can reduce copper ions in copper sulfate solution, leading to the formation of a colored copper complex. The color change usually involves a shift from blue to a range of colors, such as green or orange, depending on the specific amine and conditions.
Why does the color of copper sulfate solution changes during electrolysis?
The color change in copper sulfate solution during electrolysis occurs because copper ions from the solution are attracted to the cathode, where they are reduced to form solid copper metal. This causes the solution to turn from blue to clear as the copper ions are removed.
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 happens when you added Ammonia to copper sulfate?
When ammonia is added to copper sulfate, a blue precipitate of copper hydroxide forms, as they react to produce a complex ion. The reaction can be represented by the equation: CuSO4 + 4NH3 -> [Cu(NH3)4]SO4.
What happens when strip of zinc is dipped in copper sulphate solution?
When a strip of zinc is dipped in copper sulfate solution, a single displacement reaction occurs. Zinc, being more reactive than copper, displaces copper from the copper sulfate solution, forming zinc sulfate and depositing elemental copper on the strip. The solution changes color from blue (due to the copper sulfate) to colorless as zinc sulfate forms, and copper can be seen as a reddish-brown precipitate on the zinc strip.
