Copper Nitrate
(cupric nitrate), Cu(NO3)2; white (slightly green) crystals, which upon heating break down into CuO, NO2, and O2. Anhydrous Cu(NO3)2 can be obtained from its concentrated nitric-acid solutions. The form most often isolated from aqueous solutions is Cu(NO3)2 · 6H2O—dark blue crystals with a density of 2.07 g/cm3, which deliquesce upon exposure to air. Cu(NO3)2 · 3H2O, which forms blue crystals, is more stable at ordinary temperatures. Copper nitrate is readily soluble in water and alcohol (125.2 g anhydrous salt per 100 g H2O at 20°C) and is used in the preparation of dyes. Copper (I) nitrate can only exist in solutions, since it has not been isolated in free form. Want to thank TFD for its existence?
