1.The physicochemical properties of copper nitrate
Cu (NO3) 2 (H2O) 2.5 () 2.5, the center copper is surrounded by water molecules and nitric acid, and is coordinated by eight sides.
For the decomposition of copper oxide, nitrogen dioxide and oxygen at 170 degrees C: 2Cu (NO3) 2 (s), 2CuO (s) + 4NO2 (g) + O2 (g)
Through the thermal decomposition of copper nitrate and will produce the gas into the water to produce nitric acid. This method and the Ostwald process is similar to the last step.
2Cu (NO3) 2 + 4NO2 + O2 + 2CuO
3NO2 + 2HNO3 + NO + H2O
Soaked veneer of copper nitrate in flame issued under the emerald green light, adding nitrate will produce orange green.
Use of cupric nitrate
Analysis of strontium nitrate. Aromatic organic silicon compound nitration agent. Organic reaction catalyst.
