Cobalt Sulfate is an odorless monoclinic crystalline solid that is soluble in water, liquifying slowly around 100 °C and becoming anhydrous at 250 °C. It is slightly soluble in ethanol and very soluble in methanol.

Hydrated cobalt sulfate is incorporated in the preparation of pigments as well as in the manufacture of other cobalt salts. Cobalt pigment can be found in porcelains and glass. Cobalt sulfate is used in electroplating baths, storage batteries, sympathetic inks, and as an additive to soils and animal feeds. For these purposes, treating cobalt oxide with sulfuric acid produces the cobalt sulfate, a method of manufacturing verified in Hawley’s Condensed Chemical Dictionary 16th Edition.
