10026-24-1 Usage

Uses

Used in Chemical Industry:
Cobalt sulfate heptahydrate is used as a source of water-soluble cobalt due to its economical nature and lower tendency to deliquesce or dehydrate compared to the chloride or nitrate forms.
Used in Storage Batteries:
It is utilized in the manufacturing of storage batteries, contributing to their overall performance and efficiency.
Used in Electroplating Baths:
Cobalt sulfate heptahydrate is employed in Co-electroplating baths, enhancing the quality and properties of the electroplated coatings.
Used in Printing Industry:
It serves as a drier for lithographic inks and varnishes, ensuring proper drying and preventing issues related to moisture.
Used in Ceramics and Enamels:
Cobalt sulfate heptahydrate is used in the ceramics, enamels, and glazes industry to prevent discoloration, maintaining the desired appearance of the final products.
Used in Pigment Production:
It is used in the preparation of pigments and other cobalt salts, providing vibrant colors and enhancing the quality of the pigments.
Used in Agriculture:
Cobalt sulfate heptahydrate is added to soils and animal feeds as a supplement, promoting the health and growth of plants and animals.
Used in Sympathetic Inks:
It is employed as an additive in sympathetic inks, improving their performance and ensuring better ink flow and consistency.

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.

Check Digit Verification of cas no

The CAS Registry Mumber 10026-24-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,2 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 10026-24:
(7*1)+(6*0)+(5*0)+(4*2)+(3*6)+(2*2)+(1*4)=41
41 % 10 = 1
So 10026-24-1 is a valid CAS Registry Number.
