What is Tetraamminecopper II sulfate composition?
NSC-305303. Tetraamminecopper(II) sulfate (Cu(NH3)4SO4)
How many ligands are present in Tetraamminecopper II sulphate complex?
The IUPAC name of Cuprammonium sulfate is tetraamminecopper(II) sulfate. Now in this structure, there are four ammonia molecules directly attached with the copper. Therefore, the coordination number of copper in Cuprammonium sulfate is 4. So, the correct answer is, C.
What are the chemicals used for preparation of tetraamine copper sulphate Comlex *?
This compound can be prepared by adding concentrated solution of ammonia to a saturated aqueous solution of copper sulfate pentahydrate followed by precipitation of the product with ethanol or isopropanol.
What is Cuoxam reagent?
Cuoxam reagent solution by Research Lab Fine Chem Industries is a high grade reagent. This is a well-known solution of cupric hydroxide in aqueous ammonia. The reagent is available as a deep blue coloured solution. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents.
What is the name and formula of the blue precipitate?
Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH)2. It is a pale greenish blue or bluish green solid.
What is Switzer reagent?
Schweizer’s reagent (sometimes written as Schweitzer’s reagent) is a deep-blue solution of the coordination complex tetraammine copper(II) hydroxide, with the generally accepted formula [Cu(NH3)4(H2O)2](OH)2. This solution can be produced by dissolving copper(II) hydroxide in an excess of ammonia.
Which solution is commonly known as Cuoxam?
Cuoxam ([Cu(NH3)4](OH)2) is a blue solution of cupric hydroxide in aqueous ammonia, known since 1857 as Schweizer’s reagent.
What is tetraamminecopper (II) sulfate?
Adnan f Introduction Tetraamminecopper (II) sulfate is the inorganic compound with the formula [Cu (NH3)4 (H2O)n]SO4. This dark blue solid is a metal complex with faint odor of ammonia. It is closely related to Schweizer’s reagent, which is used for the production of cellulose fibers in the production of rayon.
What is the molecular formula for copper tetramine?

How do you test for Cu2+ in tetraamminecopper?
Often, the dark blue-violet color is used as a positive test to verify the presence of Cu 2+ in a solution. The solid state salt of tetraamminecopper (II) sulfate contains the complex ion [Cu (NH 3) 4 H 2 O] 2+, which has a square pyramidal molecular geometry.
What is tetraammine and why is it dangerous?
The characteristic deep blue colour of the tetraammine complex is found in brass and copper alloys where attack from ammonia has occurred, leading to cracking. The problem was first found in ammunition cartridge cases when they were stored near animal waste, which produced trace amounts of ammonia.
