Cobalt chloride, C0CI2. Obtained as red crystals of CoCl2 6H20 from aqueous solution, CoCU HiO and C0CI2 are blue as is the (CoCU) " ion. No higher chloride is known although cobalt-haloammines, e.g. (Co(NH3)5C1) are stable. 

Three color changes were observed blue, violet and red. From the information provided, the blue form appeared to be the anhydride, CoCl2. When exposed briefly to air containing water vapor, the anhydrous cobalt chloride turned violet, CoCl2 2H20. Upon further standing in air, the dihydrate was converted to the fully hydrated form, CoCl2 6 H20. The color of the anhydride-hydrate depended upon the relative humidity of the air to which it was exposed. 

Lange(196l), 242-3 Cobalt Chlorides Cobedtous, CoCl2 mw 129.85, dk-blue crysts, mp 735°, bp 1050°, d 3.356 gives pink solns when dissolved in cold w formed from the hexahydrate by heating it to 120°. 

The molecular weight of cobalt chloride as determined by the freezing-point method, with urethane as solvent, corresponds to the double formula, Co2Cl4 (compare ferrous chloride),1 but the results obtained by the boiling-point method 2 indicate that under those conditions the molecule is single, namely, CoCl2. 

Cobalt Oxy-chloride is obtained as a blue precipitate turning red on pouring a hot solution of cobalt chloride into dilute ammonium hydroxide. The formula CoCl2.3Co0.3-5H20, has been attributed to it.1 Another basic salt, CoC.]2.Co(OH)2.5H20, is stated to result as a precipitate by the action of calcium carbonate upon aqueous solutions of cobalt chloride.2... 

Platinum-Cobalt CS Transfer 1.246 g of potassium chlo-roplatinate (K PtClg) and 1.00 g of crystallized cobaltous chloride (CoCl2-6H20) into a 1000-mL volumetric flask, dissolve in about 200 mL of water and 100 mL of hydrochloric acid, dilute to volume with water, and mix. This solution has a color of 500 APHA units. 

Cobaltous Chloride TS Dissolve 2 g of cobaltous chloride (CoCl2-6H20) in 1 mL of hydrochloric acid and sufficient water to make 100 mL. 

Cobalt Chloride (CoCl2) supplied as a 25 mM solution with the enzyme and is stored at -20°C.
