Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2.The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. . Claims of the formation of tri- and tetrahydrates have not been confirmed
The salt is prepared with a two-step process starting with oxidizing a solution of cobalt chloride and ammonia. [1] [2]2 CoCl 2 ·6H 2 O + 10 NH 3 + 2 HCl + H 2 O 2 → 2 [Co(NH 3) 5 (OH 2)]Cl 3 + 12 H 2 O
Magenta coloured CoCl 2 ·6H 2 O. Many halides of cobalt(II) are known.e cobalt(II) fluoride (CoF 2) which is a pink solid, cobalt(II) chloride (CoCl 2) which is a blue solid, cobalt(II) bromide (CoBr 2) which is a green solid, and cobalt(II) iodide (CoI 2) which is a blue-black solid.
The compound is synthesized by the reaction of cobalt(II) chloride and ethylenediamine in hydrochloric acid in the presence of oxygen: . 4 CoCl 2 + 8 en + 4 HCl + O 2 → 4 trans-[CoCl 2 (en) 2]Cl + 2 H 2 O
Phosgene is an organic chemical compound with the formula COCl 2.It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. [7]

cis-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine).The salt consists of a cationic coordination complex and a chloride anion.
The need for an easily read humidity indicator that could not be damaged by vibration was identified during World War II. Rear Admiral Welford C. Blinn, at that time the Commander of the USS Pope, became concerned about the poor condition of the weapons and ammunition arriving in the Pacific Theater.
