| Hazard Information | Back Directory | [General Description]
Pink to red monoclinic prismatic crystals or red granular solid. Odorless. Becomes anhydrous at 788°F. | [Reactivity Profile]
Does not react strongly as either oxidizing agents or reducing agents but such behavior is not impossible. The aqueous solutions are acidic. May catalyze organic reactions. | [Air & Water Reactions]
Water soluble. The resulting solution is acidic. | [Potential Exposure]
Many be used to catalyze organic reactions. | [Fire Hazard]
Literature sources indicate that this chemical is nonflammable. | [First aid]
Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. | [Shipping]
UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. | [Incompatibilities]
Aqueous solution reacts with bases, generating some heat. May react as either oxidizing agents or reducing agents | [Chemical Properties]
Cobalt sulphate appears as pink or red crystals. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41°C and 71°C.
| [Chemical Properties]
Red powder or rose pink crystalline solid. Odorless. | [Waste Disposal]
Use a licensed professional waste disposal service to dispose of this material. All federal, state, and local environmental regulations must be observed. | [Uses]
Cobalt(II) sulfate heptahydrate is used in the preparation of pigments and other cobalt salts. It is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. | [Uses]
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. 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. | [Definition]
ChEBI: A hydrate that is the heptahydrate form of cobalt(2+) sulfate. | [Purification Methods]
Crystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. The heptahydrate crystallises below 44o and is efflorescent with m 97o . 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 pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4). |
