Cobalt nitrate is the inorganic compound with the formula Co(NO3)2.xH2O.
Cobalt nitrateis cobalt(II)'s salt.
The most common form of Cobalt nitrate is the hexahydrate Co(NO3)2·6H2O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
Cobalt nitrate Composition and structures
As well as the anhydrous compound Co(NO3)2, several hydrates of cobalt(II) nitrate exist. These hydrates have the chemical formula Co(NO3)2·nH2O, where n = 0, 2, 4, 6.
Anhydrous cobalt(II) nitrate adopts a three-dimensional polymeric network structure, with each cobalt(II) atom approximately octahedrally coordinated by six oxygen atoms, each from a different nitrate ion.
Each nitrate ion coordinates to three cobalts.
The dihydrate is a two-dimensional polymer, with nitrate bridges between Co centres and hydrogen bonding holding the layers together.
The tetrahydrate consists of discrete, octahedral [(H2O)4Co(NO3)2] molecules.
The hexahydrate is better described as hexaaquacobalt(II) nitrate, [Co(OH2)6][NO3]2, as it consists of discrete [Co(OH2)6]2+ and [NO3]− ions.
Above 55 °C, the hexahydrate converts to the trihydrate and at higher temperatures to the monohydrate.
Cobalt Nitrate is a highly water soluble crystalline Cobalt source for uses compatible with nitrates and lower (acidic) pH.
All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion.
The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Formula: NO3) for a total formula weight of 62.05.
Nitrate compounds are generally soluble in water.
Nitrate materials are also oxidizing agents.
When mixed with hydrocarbons, nitrate compounds can form a flammable mixture.
Nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials.
Cobalt Nitrate is generally immediately available in most volumes.
Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards.
Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Cobalt Nitrate Solution.
American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
Typical and custom packaging is available.
Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Technical guidance for using Cobalt Nitrate in agriculture is also available.

Cobalt nitrate Preparation
Cobalt(II) nitrate is prepared by treating the metal, or its oxide, hydroxide or carbonate with dilute nitric acid.
The solution on evaporation yields red crystals of hexahydrate:
Co + 2HNO3 → Co(NO3)2 + H2
Co(OH)2+ 2HNO3 → Co(NO3)2 + 2H2O
CoCO3+ 2HNO3→ Co(NO3)2 + CO2 + H2O.
