[edit] Properties

Anhydrous Cobalt(II)sulfate appears as red monoclinic crystals that melt at 96.8°C and become anhydrous at 420°C. It is soluble in water, slightly soluble in ethanol, and especially soluble in methanol. ^[1]

[edit] Uses

It is used the preparation of pigments, as well as in the manufacture of other cobalt salts. Cobalt pigment is used in porcelains and glass. Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds.^[2] In the past, Cobalt(II) Sulfate was used to improve the stability of foam in beer and to treat some forms of anemia not responsive to other treatments.^[3]
