What do you get if mix copper and oxygen?
When copper is mixed with oxygen, copper oxide is formed. The specific compound formed depends on the ratio of copper to oxygen present during the reaction.
Why does copper sulphate and sodium carbonate mixed together turn green?
When copper sulfate (blue) and sodium carbonate (colorless) are mixed, a chemical reaction occurs that forms copper carbonate as a product, which is green in color. The green color comes from the copper carbonate that is insoluble in water and precipitates out when the two solutions are mixed.
If solid copper sulfate is mixed with water what is formed?
a copper sulfate solution it becomes copper (II) sulfate pentahydrate
Why does copper chloride solution appear to fade in color when mixed with aluminum?
When copper chloride solution is mixed with aluminum, a redox reaction occurs where the aluminum reduces the copper ions to form copper metal. This results in a color change from blue-green (copper chloride solution) to colorless (copper metal precipitate), giving the appearance of fading in color due to the formation of a solid copper instead of a colored solution.
What reaction occurs from a mixture of CuO and concentrated HCl?
When concentrated Hydrogen chloride acid is made to react with Copper(II)Oxide, Copper Chloride is formed with the evolution of a greenish yellow pungent gas called chlorine(Cl 2).The chlorine gas formed turns moist starch iodide paper blue black.turns blue litmus red and finally decolourizes it. Copper oxide used here is black in color.
What is formed when copper oxide and nitric acid is mixed together?
copper nitrate
Is copper chloride mixture?
No, copper chloride is a pure substance.

What is the reaction when you mix copper chloride and ammonium hydroxide?
This is an addition reaction that is also a complexing reaction. The ammonia complexes the copper and acts as a ligand. Tetra-amine Copper Chloride is formed which is a deep inky blue color. [Cu(NH3)4]2+ [Cl-]2 + 4H2O
How do you tell the difference between brass and copper?
The brass has much lighter color (yellowish to light reddish), then the copper (reddish brown). The brass is copper mixed with zinc. The more copper in the mix, the darker the color.
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 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 is the color when fehling a and fehling b are being mixed?
When Fehling A & B are mixed in equal quantities... Fehlings Reagent is formed which is DEEP BLUE in colour Hope that answers your question! :)
