Copper(II) nitrate, commonly referred to as 'copper nitrate', is a blue, crystalline solid at STP. The roman numeral sign is to specify the oxidation state of the copper, in this case a +2 charge. Copper nitrate is commonly used in school laboratories to demonstrate chemical voltaic cell reactions.
Properties
Copper(II) Nitrate decomposes when heated to 170C into Copper(II) Oxide, Nitrogen Dioxide and Oxygen:
Cu(NO3)2 -> CuO + NO2 + O2<P> Copper Nitrate can be used to create Nitric Acid by heating it until decomposition and pushing the fumes directly into water. This is like the last step in the Ostwald process. The formula is as follows:<P> Cu(NO3)2 -> CuO + NO2 + O2<P> 4 NO2 + O2 + 2 H2O -> 4 HNO3<P>
- molecular formula: Cu(NO3)2
- appeareance: Blue Crystals
- odor: odorless
- boiling point (decomposes): 170°C
- melting point: 115°C
- soluble in water
- molar mass/Formula Weight: 187.56 g/mol
- additional properties
- stable oxidant
- harmful by inhalation
- exposure to dust can irritate nose, throat and eyes.
