More Details About The Product


Cobalt Sulphate, also called as Cobalt(II) sulfate, is salt of cobalt when referred to the hydrate CoSO4.7H2O. When used with neutralize bases, it reacts as acids. This inorganic compound with CoSO4(H2O)x formula has red monoclinic crystals like appearance. These crystals can melt at temperature around 100 °C, while these become anhydrous at temperature 250 °C.

CoSO4 is soluble in water at 20°C, methyl alcohols and slightly in ethyl. With a 3.71 g/cm3 (anhydrous) and 1.948 g/cm3 (heptahydrate) density, Cobalt Sulphate is prepared when aqueous sulfuric acid, cobalt metal and its oxide/ hydroxide react. Cobalt sulfate can be formed in hydrated form by heating the solution that drives off the water. Hydrated crystals can be heated at 250°C temperature to drive off the water in the formation process of anhydrous cobalt(II) sulfate.

This inorganic compound is not safe for the environment and is harmful for humans if gets in direct contact or inhaled.

Applications of Cobalt Sulphate

Cobalt(II) sulfate finds use in sympathetic inks, electroplating baths and storage batteries. It can be used as an additive to animal feed and soil. Pigments can be prepared using hydrated cobalt(II) sulfate. Cobalt pigment is used for coloring glass and porcelains.
