2 AgNO 3 + Cu → Cu(NO 3) 2 + 2 Ag. Silver nitrate decomposes when heated: 2 AgNO 3 (l) → 2 Ag(s) + O 2 (g) + 2 NO 2 (g) Qualitatively, decomposition is negligible below the melting point, but becomes appreciable around 250 °C and fully decomposes at 440 °C. [9]
No mineral of the ideal Cu(NO 3) formula, or the hydrates, are known. Likasite, Cu 3 (NO 3)(OH) 5 ·2H 2 O and buttgenbachite, Cu 19 (NO 3) 2 (OH) 32 Cl 4 ·2H 2 O are related minerals. [21] [22] Natural basic copper nitrates include the rare minerals gerhardtite and rouaite, both being polymorphs of Cu 2 (NO 3)(OH) 3.
The method is illustrated by the route to β-Cu(NO 3) 2: Cu + 2 N 2 O 4 → Cu(NO 3) 2 + 2 NO. Many metals, metal halides, and metal carbonyls undergo similar reactions, but the product formulas can be deceptive. For example from chromium one obtains Cr(NO 3) 3 (N 2 O 4) 2, which was shown to be the salt (NO +) 2 [Cr(NO 3) 5] 2-. [15]

Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...
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 ...
