[structure or molecular formula] CoCl 2 ·6H 2 O [density] relative density (25 ° C): 1.925 (six water), 3.356 (anhydrous) [melting point (°C)] 86 (six water) ã€Properties】 Hexahydrate: red crystal, anhydrate: light blue powder. ã€Solubility】 Liushui: soluble in water, soluble in ethanol, ether and acetone; anhydrous: soluble in ethanol, acetone, nitrobenzene. ã€use】 Used in the manufacture of barometers, hydrometers, hidden inks, etc. The cobalt chloride test paper is blue when dry and turns pink when wet. A certain amount of cobalt chloride is added to the silica gel to indicate the degree of moisture absorption of the silica gel. [preparation or source] It is prepared by the action of cobalt oxide and hydrochloric acid. ã€other】 The hexahydrate is deliquescent in the air, and when it is heated to 120-140 ° C, it loses crystal water and becomes an anhydrate.
