Anhydrous Cu(NO 3) 2 is one of the few anhydrous transition metal nitrates. [9] It cannot be prepared by reactions containing or producing water. Instead, anhydrous Cu(NO 3) 2 forms when copper metal is treated with dinitrogen tetroxide: [6] Cu + 2 N 2 O 4 → Cu(NO 3) 2 + 2 NO
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
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(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.
Yttrium(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO 3 is formed. [2] At 600 C, the thermal decomposition is complete. Y 2 O 3 is the final product. [3] Y(NO 3) 3 ·3TBP is formed when tributyl phosphate is used as the extracting solvent. [4]
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).
Praseodymium(III) nitrate is any inorganic compound with the chemical formula Pr(NO 3) 3 ·xH 2 O. These salts are used in the extraction and purification of praseodymium from its ores. [2] The hexahydrate has been characterized by X-ray crystallography. [3] Praseodymium nitrate can be prepared by treating praseodymium oxide with nitric acid:
