Cobalt nitrate is a chemical salt formed from the metal cobalt and the nitrate ion. It is an oxidizer and is soluble in water. The molecular formula is Co(NO3)2
It is deliquescent in moist air and soluble in most polar solvents. It is derived from reacting metallic cobalt or one of its oxides, hydroxides, or carbonate with nitric acid. It is commonly used in dyes and inks.[1]
The high solubility of cobalt nitrate makes it a common source of cobalt in metal-organic frameworks and polymers. It is also reduced to metallic cobalt or precipitated on various substrates for Fischer-Tropsch catalysis.[2]
