Cobalt nitrate Chemical Properties,Usage,Production

Uses Cobalt nitrate is used in the decoration of porcelain and stones; in the manufacture of invisible inks and cobalt pigments; in hair dyes; in animal feeds; as an additive to soils; in catalysts preparation; and in vitamin supplements.
Chemical Properties Red crystals. Deliquescent in moist air. Soluble in most organic solvents.
Physical properties The hexahydrate is red monoclinic crystal; deliquescent in moist air; density 1.87 g/cm³; decomposes at 55°C, losing three molecules of water; decomposes to green cobalt(II) oxide on further heating at 74°C; very soluble in water (134 g/100mL at 0°C); also soluble in alcohols and acetone. The anhydrous salt is pale red powder; density 2.49 g/cm³; decomposes around 100°C; soluble in water.
Uses Sympathetic inks, cobalt pigments, catalysts, additive to soils and animal feeds, vitamin preparations, hair dyes, porcelain decoration.
Uses Cobalt(II) Dinitrate is mainly reduced to metallic high purity cobalt used for catalysis reactions.
Definition ChEBI: A cobalt salt in which the cobalt metal is in the +2 oxidation state and the counter-anion is 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.
General Description Odorless red solid. Sinks and mixes with water.
Air & Water Reactions Water soluble.
Reactivity Profile Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride or other reducing agents may react explosively [Bretherick, 1979 p. 108-109].
Hazard Oxidizing agent, dangerous fire risk in contact with organic materials.
Health Hazard Inhalation causes shortness of breath and coughing; permanent disability may occur. Ingestion causes pain and vomiting. Contact with eyes or skin causes irritation.
Flammability and Explosibility Not classified
