What is COBALT(II) SULFATE HYDRATE?
Chemical properties
Reddish crystalline powder
The Uses of COBALT(II) SULFATE HYDRATE
Cobalt(II) sulfate hydrate (CoSO4.H2O) can be used in the synthesis of coordination polymers. It can also be used as a starting material in the synthesis of cobalt sulfides hexagonal nanocrystallites.
The Uses of COBALT(II) SULFATE HYDRATE
Ceramics, pigments, glazes, plating baths, catalyst, storage batteries, paint/ink drier
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).
