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.
