10026-24-1 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 10026-24-1 differently. You can refer to the following data:
1. Cobalt sulphate appears as pink or red crystals. It is stable, non-flammable, and hygroscopic and undergoes dehydration at 41°C and 71°C.
2. Red powder or rose pink crystalline solid. Odorless.
Uses
Different sources of media describe the Uses of 10026-24-1 differently. You can refer to the following data:
1. 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.
2. 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.
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.
