Нитрата меди

Molecular formula: Cu(NO3)2.3H2O Molecular weight: 241.60 Physicochemical properties: 1) Cupric nitrate has three kinds of hydrates-trihydrate, hexahydrate and nonahydrate 2) The trihydrate is a dark blue columnar crystal 3) Specific dnsity: 2.05 4) Melting pint: 114.5°C 5) Degraded into an insoluble basic salt: Cu(NO3)2l Cu(OH)2 when heated at 170°C, and then convert into copper oxide 6) It is apt to dissolve in water and ethanol 7) The aqueous solution is acidity and the hydrate is easy in moisture absorption. Cupric nitrate is a strong oxidizer which can cause burning and explosive if heated, rubbed or impacted with carbon powder, sulfur or other combustible materials 8) Application and usage: cupric nitrate is used as catalyst, oxidizer, activating agent for luminescent powder, and photosensitive resistance material.
