Copper(II) nitrate describes any member of the family of inorganic compounds with the formula Cu(NO 3) 2 (H 2 O) x.The hydrates are hygroscopic blue solids. Anhydrous copper nitrate forms blue-green crystals and sublimes in a vacuum at 150-200 °C.
CuO + 2 HNO 3 → Cu(NO 3) 2 + H 2 O CuO + 2 HCl → CuCl 2 + H 2 O CuO + H 2 SO 4 → CuSO 4 + H 2 O. In presence of water it reacts with concentrated alkali to form the corresponding cuprate salts: 2 NaOH + CuO + H 2 O → Na 2 [Cu(OH) 4] It can also be reduced to copper metal using hydrogen, carbon monoxide, and carbon: CuO + H 2 → Cu + H ...
Copper azide can be prepared by a metathesis reaction between water-soluble sources of Cu 2+ and azide ions. (Spectator ions omitted in reaction below). Cu 2+ + 2 N − 3 → Cu(N 3) 2. It can be destroyed by concentrated nitric acid to form non-explosive products, these being nitrogen, nitrogen oxides and copper(II) nitrate.
The tetrahydrate consists of discrete, octahedral [(H 2 O) 4 Co(NO 3) 2] molecules. The hexahydrate is better described as hexaaquacobalt(II) nitrate, [Co(OH 2) 6][NO 3] 2, as it consists of discrete [Co(OH 2) 6] 2+ and [NO 3] − ions. [5] Above 55 °C, the hexahydrate converts to the trihydrate and at higher temperatures to the monohydrate. [2]
Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH) 2.It is a pale greenish blue or bluish green solid. Some forms of copper(II) hydroxide are sold as "stabilized" copper(II) hydroxide, although they likely consist of a mixture of copper(II) carbonate and hydroxide.
The nitrate salt of the acetonitrile complex, i.e., [Cu(MeCN) 4]NO 3, is generated by the reaction of silver nitrate with a suspension of copper metal in acetonitrile. [2] Cu + AgNO 3 + 4 CH 3 CN → [Cu(CH 3 CN) 4]NO 3 + Ag. Tertiary phosphine complexes of the type [Cu(P(C 6 H 5) 3) 3]NO 3 are prepared by the reduction of copper(II) nitrate by ...
Tetraamminecopper(II) sulfate monohydrate, or more precisely tetraammineaquacopper(II) sulfate, is the salt with the formula [Cu(N H 3) 4]S O 4 ·H 2 O, or more precisely [Cu(NH 3) 4 (H 2 O)]SO 4. This dark blue to purple solid is a sulfuric acid salt of the metal complex [Cu(NH 3) 4 (H 2 O)] 2+ (tetraammineaquacopper(II) cation).
Iron(III) nitrate is deliquescent, and it is commonly found as the nonahydrate Fe(NO 3) 3 ·9H 2 O, which forms colourless to pale violet crystals. This compound is the trinitrate salt of the aquo complex [Fe(H 2 O) 6] 3+. [4] Other hydrates Fe(NO 3) 3 ·x H 2 O, include:
