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)
A insoluble solid is formed and a neon blue liquid floats to the surface.it is a precipitate displacement reaction.
Deep blue solution formed containing complex ion Cu[(NH3)4 ]2+
Pale blue precipitate is formed....n it is soluble in excess of ammonium hydroxide
You mean ammonium hydroxide? Ammonia is gaseous, dear. It's not a salt. Ammonium hydroxide reacts with copper sulphate to give ammonium sulphate and copper hydroxide.
When it is added it turns from a dark blue color to a light blue color! Hope that helps
an aqueous solution of copper sulphate is homogeneous
no reaction would take place
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Blue
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
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
well, ammonia is a very hot country and there is really loads of stuff there :0
A precipitate is formed which has a light blue colour. After shaking, the precipitate re-dissolves forming a dark blue solution.
the solution turns green and the nails develop a brown deposit which is copper. the iron displaces the copper in the copper sulphate solution. This is because iron is more reactive than copper.

Nothing
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
an aqueous solution of copper sulphate is homogeneous
silicate, carbonate or sulphate
Yes, copper sulphate(CuSO4) can be separated from its solution in crystalline form.
