Specifications

Copper Nitrate
Product Description
Product Name: Copper Nitrate
Purity: 98% min
Grade: Industrial grade; Reagent grade
CAS No. : 3251-23-8; 13478-38-1; 10402-29-6
HS Code: 28342990
Molecular Formula: Cu(NO3)2.3H2O
Apperance: Dark blue crystal
Standard: HG3-931-76
Synonyms: Cupric Nitrate; Cuprous Nitrate; Copper Dinitrate; Cupric nitrate, n-hydrate; Nitric Acid, Copper (2+) salt; Kupferdinitrat(German); Dinitrato de cobre(Spanish); Dinitrate de cuivre(French)
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
5) Degraded into an insoluble basic salt: Cu(NO3)2l Cu(OH)2 when heated at 170& deg; 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.
