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. [5] [6] Common hydrates are the hemipentahydrate and trihydrate.
Thus copper(II) nitrate readily dissociates in aqueous solution to give the aqua complex: Cu(NO 3) 2 + 6 H 2 O → [Cu(H 2 O) 6](NO 3) 2. Pyrolysis of metal nitrates yields oxides. [18] Ni(NO 3) 2 → NiO + NO 2 + 0.5 O 2. This reaction is used to impregnate oxide supports with nickel oxides. Nitrate reductase enzymes convert nitrate to
Many other oxyanions form complexes; these include copper(II) acetate, copper(II) nitrate, and copper(II) carbonate. Copper(II) sulfate forms a blue crystalline pentahydrate, the most familiar copper compound in the laboratory. It is used in a fungicide called the Bordeaux mixture. [3] Ball-and-stick model of the complex [Cu(NH 3) 4 (H 2 O) 2 ...
For example, Cu + is copper(I), Cu 2+ is copper(II). An older, deprecated notation is to append -ous or -ic to the root of the Latin name to name ions with a lesser or greater charge. Under this naming convention, Cu + is cuprous and Cu 2+ is cupric. For naming metal complexes see the page on complex (chemistry).
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).
A chemical garden is a set of complex biological-looking structures created by mixing inorganic chemicals. This experiment in chemistry is usually performed by adding metal salts, such as copper sulfate or cobalt(II) chloride, to an aqueous solution of sodium silicate (otherwise known as waterglass). This results in the growth of plant-like ...

The solid state structure of tetraamminecopper(II) sulfate monohydrate confirms that the compound is a salt. The complex cation is [Cu(NH 3) 4 (H 2 O)] 2+ (tetraammineaquacopper(II) cation), which has a square pyramidal molecular geometry. The Cu-N and Cu-O bond length are about 210 and 233 pm, respectively, as determined by X-ray ...
