![]() ![]() Use a licensed professional waste disposal service to dispose of this material. May react as either oxidizing agents or reducing agents Waste Disposal IncompatibilitiesĪqueous solution reacts with bases, generating some heat. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4). Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The heptahydrate crystallises below 44o and is efflorescent with m 97o. Purification MethodsĬrystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1 Labels: 6.1-Poisonous materials, Technical Name Required. Many be used to catalyze organic reactions. Literature sources indicate that Cobalt sulfate heptahydrate is nonflammable. Reactivity Profileĭoes not react strongly as either oxidizing agents or reducing agents but such behavior is not impossible. Pink to red monoclinic prismatic crystals or red granular solid. DefinitionĬhEBI: A hydrate that is the heptahydrate form of cobalt(2+) sulfate. It is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. UsesĬobalt(II) sulfate heptahydrate is used in the preparation of pigments and other cobalt salts. ![]() Used in storage batteries in Co-electroplating baths as drier for lithographic inks, varnishes in ceramics, enamels, glazes to prevent discoloring in Co pigments for decorating porcelain. Usual source of water-soluble cobalt since it is the most economical and it shows less tendency to deliquesc or dehydrate than the chloride or nitrate. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41☌ and 71☌. Chemical PropertiesĬobalt sulphate appears as pink or red crystals. Red powder or rose pink crystalline solid. ![]()
