Uses

Cobaltous chloride (CAS NO.7646-79-9) is common used for the detection of moisture, for example in drying agents such as silica gel. When cobalt(II) chloride is added as an indicator, the drying agent is pink when exhausted,blue when still active, corresponding to anhydrous and hydrated CoCl₂, respectively. Similarly, "cobalt chloride paper",that is paper impregnated with cobalt chloride,is used to detect the presence of water. The rose hexahydrate of it is one of the most common cobalt compounds in the laboratory.

Production

Cobaltous chloride (CAS NO.7646-79-9) can be prepared in its anhydrous form from cobalt metal and chlorine gas:
Co (s) + Cl₂ (g) → CoCl₂ (s)
The hydrated form of Cobalt(II) chloride (7646-79-9) can be prepared from cobalt(II) hydroxide or cobalt(II) carbonate and hydrochloric acid :
Co₂+ (aq) + 2Cl− (aq) → CoCl₂ (aq)

HazardClass: 8
PackingGroup: III
Poison experimentally by ingestion, skin contact, intraperitoneal, intravenous, and subcutaneous routes. Moderately toxic to humans by ingestion. Human systemic effects by ingestion: anorexia, goiter (increased thyroid size), and weight loss. Experimental teratogenic and reproductive effects. When heated to decomposition it emits toxic fumes of Cl⁻.

Specification

The term " Cobaltous chloride " is used also to refer to the hexahydrate,CoCl₂ is blue, and CoCl₂·6H₂O is deep rose.CoCl₂·6H₂O is deliquescent and the anhydrous salt CoCl₂ is hygroscopic, readily converting to the hydrate.
The existence of Cobalt(III) chloride , CoCl₃, is disputed, although it is listed in some compendia.
Other informations about Cobaltous chloride (CAS NO.7646-79-9):
