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
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.
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.
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.
When aluminum is mixed with copper sulfate, the aluminum reacts with the copper ions in the copper sulfate solution and displaces the copper, forming aluminum sulfate and copper metal. Magnesium does not play a direct role in this reaction.
When iron is added to copper sulfate, a displacement reaction occurs where the iron displaces the copper in the compound to form iron sulfate and copper metal. This reaction results in a color change from blue (copper sulfate) to green (iron sulfate) as the copper ions are replaced by the iron ions.

When water is added to white copper sulfate (CuSO4), it dissolves and forms a blue-colored solution. This reaction is reversible, as the blue color disappears when the water evaporates and the white copper sulfate crystals are left behind.

When iron is added to copper sulfate, a displacement reaction occurs where the iron displaces the copper in the compound to form iron sulfate and copper metal. This reaction results in a color change from blue (copper sulfate) to green (iron sulfate) as the copper ions are replaced by the iron ions.
Why does copper sulfate change its colour when water is added
When water is added to anhydrous copper (II) sulfate, it will undergo an exothermic reaction where the compound absorbs water molecules to form hydrated copper (II) sulfate. The anhydrous copper (II) sulfate changes color from white to blue as it forms the hydrate.
Nothing happens, because positive metal ions (Cu2+ and Na+ ) never will react with each other.
When copper sulfate is added to water, it dissolves and forms a blue solution. The copper ions (Cu2+) and sulfate ions (SO4 2-) are dispersed in the water, making a homogeneous mixture. This solution can be used for various applications, such as in agriculture as a fungicide or in chemistry experiments.
