Cobalt sulfate heptahydrate Chemical Properties,Usage,Production

Chemical Properties

Red powder or rose pink crystalline solid. Odorless.

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.

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.

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.

Definition

ChEBI: A hydrate that is the heptahydrate form of cobalt(2+) sulfate.

General Description

Pink to red monoclinic prismatic crystals or red granular solid. Odorless. Becomes anhydrous at 788°F.

Air & Water Reactions

Water soluble. The resulting solution is acidic.

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.

Fire Hazard

Literature sources indicate that Cobalt sulfate heptahydrate is nonflammable.

Potential Exposure

Many be used to catalyze organic reactions.

Shipping

UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

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).

Incompatibilities

Aqueous solution reacts with bases, generating some heat. May react as either oxidizing agents or reducing agents

Waste Disposal

Use a licensed professional waste disposal service to dispose of this material. All federal, state, and local environmental regulations must be observed.
