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
Cu(OH)2
6 atoms
answer is Cu(OH)3
Answer: Cupric hydroxide (as bluish white precipitate) and sodium nitrate. Cu(NO3)2 + 2NaOH --> Cu(OH)2 + 2NaNO3
(Cu(NH 3 ) 4 . (OH) 2 ) A solution of cupric hydroxide in aqueous ammonium hydroxide
Copper(II) hydroxide can be called also cupric hydroxide.The first is the recommended IUPAC name.
