5 atoms = 1 Copper + 2 Hydrogen + 2 Oxygen
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
Answer: Cupric hydroxide (as bluish white precipitate) and sodium nitrate. Cu(NO3)2 + 2NaOH --> Cu(OH)2 + 2NaNO3
The formula for cupric hydroxide is Cu(OH)2. It consists of one copper (Cu) ion bonded to two hydroxide (OH) ions.
answer is Cu(OH)3
Copper(II) hydroxide can be called also cupric hydroxide.The first is the recommended IUPAC name.

Cupric sulfate, also known as copper(II) sulfate, has the chemical formula CuSO4. It contains one copper atom (Cu), one sulfur atom (S), and four oxygen atoms (O) in one molecule. So, there are a total of six atoms in one molecule of cupric sulfate.
9 atoms = 1 Copper + 2 Nitrogen + 6 Oxygen
(Cu(NH 3 ) 4 . (OH) 2 ) A solution of cupric hydroxide in aqueous ammonium hydroxide
When solid cupric nitrate reacts with aqueous potassium hydroxide, the following chemical reaction occurs: Cu(NO3)2 + 2KOH -> Cu(OH)2 + 2KNO3. The deep blue precipitate formed is cupric hydroxide (Cu(OH)2), which is insoluble in water and thus appears as a solid in the test tube.
There are 4 hydrogen atoms in ammonium hydroxide (NH4OH).
NH4OH has 7 atoms
