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. [4] The anhydrous form is a blue crystalline solid; the dihydrate is purple and the ...
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 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
trans-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine). It is a green diamagnetic solid that is soluble in water. It is the monochloride salt of the cationic coordination complex [CoCl 2 (en) 2] +. One chloride ion in this salt readily undergoes ion exchange but the two other ...
Chemical nomenclature is a set of rules to generate systematic names for chemical compounds.The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
Americans are obsessed with a white Christmas and all the trimmings – snow, icicles, sleigh rides, frost on windowpanes, cuddling up by the fire, mittens, the North Pole.
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] It can be thought of chemically as the double acyl chloride analog of carbonic acid, or structurally as formaldehyde with the hydrogen atoms replaced by chlorine atoms.
Another witness, identified only by his last name, Cho, told the outlet he was taking a walk 4.5 kilometers, or about 2.8 miles, from the airport when the plane crashed into the concrete wall at ...
