Cobalt(II) sulfate heptahydrate. Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO 4 (H 2 O) x.Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO 4. 6H 2 O or CoSO 4. 7H 2 O, respectively. [1]
Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al 2 (SO 4) 3 ·16H 2 O and octadecahydrate Al 2 (SO 4) 3 ·18H 2 O are the most common. The heptadecahydrate, whose formula can be written as [Al(H 2 O) 6] 2 (SO 4) 3 ·5H 2 O, occurs naturally as the ...
Oleums can be described by the formula ySO 3 ·H 2 O where y is the total molar mass of sulfur trioxide content. The value of y can be varied, to include different oleums. They can also be described by the formula H 2 SO 4 ·xSO 3 where x is now defined as the molar free sulfur trioxide content. Oleum is generally assessed according to the free ...
The barium derivative is useful in the gravimetric analysis of sulfate: if one adds a solution of most barium salts, for instance barium chloride, to a solution containing sulfate ions, barium sulfate will precipitate out of solution as a whitish powder. This is a common laboratory test to determine if sulfate anions are present.
The solution is purged with air to oxidize the cobalt(II)-ethylenediamine complexes to cobalt(III). The reaction proceeds in 95% yield, and the trication can be isolated with a variety of anions. A detailed product analysis of a large-scale synthesis revealed that one minor by-product was [Co(en) 2 Cl(H 2 NCH 2 CH 2 NH 3 )]Cl 3 , which contains ...
Cobalt(II) oxide, CoO, converts to Co 3 O 4 upon heating at around 600–700 °C in air. [4] Above 900 °C, CoO is stable. [4] [5] These reactions are described by the following equilibrium: 2 Co 3 O 4 ⇌ 6 CoO + O 2
Thiosulfate is an acceptable common name and used almost always. The functional replacement IUPAC name is sulfurothioate; the systematic additive IUPAC name is trioxidosulfidosulfate(2−) or trioxido-1κ 3 O-disulfate(S—S)(2−). [1] Thiosulfate also refers to the esters of thiosulfuric acid, e.g. O,S-dimethyl thiosulfate CH 3 −O−S(=O) 2 ...
