Cobalt(III) nitrate can be prepared by the reaction of dinitrogen pentoxide N 2 O 5 with cobalt(III) fluoride CoF 3. [3] It can be purified by vacuum sublimation at 40 °C. [4] [2] Cobalt(III) nitrate oxidizes water, the initial green solution rapidly turns pink, with formation of cobalt(II) ions and release of oxygen. [1]
Cobalt can easily react with nitric acid to form cobalt(II) nitrate Co(NO 3) 2. Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [12] and its molecule contains cobalt ...
Cobalt nitrate can refer to: Cobalt(II) nitrate and its several hydrates; Cobalt(III) nitrate, a diamagnetic volatile compound This page was last edited on 14 May ...
Cobalt nitrate is the inorganic compound with the formula Co(NO 3) 2. xH 2 O. It is cobalt (II)'s salt . The most common form is the hexahydrate Co(NO 3 ) 2 ·6H 2 O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.

Metal nitrito complexes figure prominently in the nitrogen cycle, which describes the relationships and interconversions of ammonia up to nitrate. Because nitrogen is often a limiting nutrient, this cycle is important. Nitrite itself does not readily undergo redox reactions, but its metal complexes do. [13]
The salt is prepared with a two-step process starting with oxidizing a solution of cobalt chloride and ammonia. [1] [2] 2 CoCl 2 ·6H 2 O + 10 NH 3 + 2 HCl + H 2 O 2 → 2 [Co(NH 3) 5 (OH 2)]Cl 3 + 12 H 2 O. This intermediate is then heated to induce coordination of one of the outer sphere chloride ligands: [Co(NH 3) 5 (OH 2)]Cl 3 → [Co(NH 3 ...
An aqueous solution of cobalt(II) nitrate and hydrogen peroxide is added to a solution of sodium bicarbonate, leading to precipitation of the olive solid. [2] The method is a modification of the synthesis of what has been described as “Co 2 (CO 3 ) 3 ”.
