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
This has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base and special plastic films. [1] Humidity indicators are an inexpensive way to indicate or quantify moisture content inside sealed packaging. They are available in many configurations ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis .
Cobalt can easily react with nitric acid to form cobalt(II) nitrate Co(NO 3) 2. Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [12] and its molecule contains cobalt ...
CoCl 2 ·6H 2 O – cobalt(II) chloride hexahydrate SnCl 2 ·2H 2 O – tin(II) ( or stannous) chloride dihydrate For many salts, the exact bonding of the water is unimportant because the water molecules are made labile upon dissolution.
A common oxidation state for simple compounds is +2 (cobalt(II)). These salts form the pink-colored metal aquo complex [Co(H 2 O) 6] 2+ in water. Addition of chloride gives the intensely blue [CoCl 4] 2−. [7] In a borax bead flame test, cobalt shows deep blue in both oxidizing and reducing flames. [20]
Standards can be bought pre-mixed or made by following guidelines prepared by the American Society for Testing and Materials' (ASTM). The mixture itself is an acidic solution of potassium hexachloro- platinate(IV) and cobalt(II) chloride with different levels of dilution for intermediate steps. [4] The procedure to using APHA color is as follows:
