Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
If a sample of ammonia gas were bubbled into aqueous copper (II) sulfate until no further change took place, you would observe a deep blue color forming due to the formation of a complex copper-ammonia compound. This complex, [Cu(NH3)4(H2O)2]2+, is responsible for the color change.
No, the addition of extra ammonia will not dissolve Copper II sulfide. Copper II sulfide is insoluble in water and ammonia solution; it does not react with ammonia to form soluble complexes.
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
To write the chemical equation for this reaction, it would be: CuO(s) + H2SO4(aq) -> CuSO4(aq) + H2O(l). This reaction involves the solid copper II oxide reacting with the aqueous sulfuric acid to form aqueous copper II sulfate and water.
The precipitate of copper II hydroxide is initially blue-green. When aqueous ammonia is added, the precipitate dissolves to form a deep blue solution due to the formation of a complex ion called tetraamminecopper (II) complex.
Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
You can separate unreacted copper II carbonate from aqueous copper II chloride by filtration. The copper II carbonate is insoluble in water, so it can be filtered out using a filter paper. The aqueous copper II chloride solution can then be collected separately.

You can separate water from aqueous copper(II) sulfate through a process called evaporation. Heat the solution to allow the water to evaporate, leaving behind the solid copper(II) sulfate. This is an effective way to isolate the two components.
Sounds like copper (II) sulfate (ie cupric sulfate or CuSO4)
Copper(II) chromate can be prepared by reacting a solution of sodium chromate with a solution of copper(II) sulfate. The resulting precipitate is then filtered and dried to obtain solid copper(II) chromate.
Yes, copper II hydroxide is a base. It is an insoluble base that forms when copper ions react with hydroxide ions in an aqueous solution, leading to the precipitation of the copper II hydroxide compound.
When copper ions react with ammonium chloride, a white precipitate of copper(I) chloride forms due to the oxidation of copper(II) ions by ammonia. This reaction is accompanied by the liberation of ammonia gas, which can be detected by its characteristic odor.
